When we first clapped eyes Powerfreakz's Evolution 2500 we were excited as we’re a big fan of the whole wireless charging bandwagon. Then we realised it wasn’t actually a wireless charger at all and our feelings went from glee to underwhelmed.

Fast forward a few hours and our opinion changed somewhat. Yes, you could argue that you don’t need a portable charger for your iPhone – or phone for that matter – if you carry your cable around and have access to a computer, but that’s not ideal if you’re limited for space.

The actual charger itself is fairly svelte. It’s a rectangular tablet in appearance with vital statistics measuring in at 59mmx100mmx10 (WLH) and weighing just 88g. The product comes in a clear plastic box with the charger clearly visible towards the top of the packaging. Underneath you’ll find – hidden beneath an inner cardboard box – a carry case for the device with a power supply and umpteen types of connector tips.

Handily, in addition to a three-pin UK plug, European and US power supply adaptors are also included, which should come in handy if you find yourself abroad with no standard way of charging your phone – we’ve all been there.

All you need to do is charge up the Powerfreakz Evolution 2500 (making use of the power supply or the USB port of a computer and the charger’s in socket) and then you’re ready to charge your chosen device. You simply need to root around in the pile of assorted connectors and find the one that’s right for you. Once you’ve done that, connect it up to the out socket and press the on button.

The green LED light surrounding the Powerfreakz logo will illuminate to show it’s working and you’re phone/other device will also indicate that it has juice flowing through it. When you’re done, just hit off and pack the connector tips and USB cable away in the carry case.

According to Powerfreakz, the Evolution 2500 Portable Charger can inject an impressive amount of juice into a range of devices. For example, you can apparently extend the life of an iPod or MP3 player by an extra two days and take another 2,000 pictures on a digital camera (we assume this is a compact rather than SLR using RAW mode).

We tested the charger using a mobile phone and it did an impressive job of charging the battery, although we're not sure if it would charge a smartphone with a hefty battery such as the Google Nexus One, iPhone or any other device that has anything over a 1300mAh as effectively.

The Powerfreakz Evolution 2500 Portable Charger is a handy device to boost the power of you electronics, but you'll just have ensure it's always fully charged to avoid that low battery panic.

If you’re a phone fan, there’s a good chance you’ll use your mobile as much more than just a talk and text machine. Even if it’s just as a pocket clock, it’s almost hard to use a modern phone as a single function device – you really have to try pretty hard.

The CDS-75 Deskstand from Sony Ericsson is designed to help you along the road to real mobile phone appreciation – think of it as a less intensive road to enlightenment. It will hold your Sony Ericsson phone upright, letting you find out what’s up with your phone without having to delve into your pocket, or even pick the thing up.

As different Sony Ericsson phones have their charge sockets placed at different spots along their bodies, the arm that holds the plug to jack into your phone features a slider that can be moved up and down freely. The CDS-75 Deskstand acts as a charger as well as a stand, although the included charger is a bog standard one rather than anything fully integrated into the stand itself.

The stand structure is made up of two main bits – the base and the slider arm. They slot into each other and the base has a rubberised bottom that’ll offer that little bit of extra friction to keep it in place on your desk.

However, it still isn’t exactly what we’d call robust. The CDS-75 Deskstand holds your phone with a light touch rather than gripping it. Knock it with a careless elbow and the whole lot will keel over pretty easily. Perhaps we’ve been spoilt by the legions of iPhone docks we’ve had our hands on over the last couple of years, but by comparison the CDS-75 feels like a bit of a makeshift solution.

Is it good value though? Well, the CDS-75 Deskstand does include a charger, but then we wouldn’t pay much more than a fiver for one of those. So, you’re still paying a fair bit more than a tenner for what amounts to not all that much.

The CDS-75 Deskstand suffers from a similar condition as some other official Sony Ericsson accessories – for its price it can’t stand up proud and tall against some 3rd party alternatives. Still, we can’t ignore the fact that it is specifically designed for Sony Ericsson devices, where other solutions will grip each side of your device – a bit less elegantly.

You do need to make sure that your phone’s charging socket is on its left-hand side though. While it can cope with bottom-loaded phones like the classic K750i, the CDS-75 doesn’t look nearly as good as the sliding arm bit still pokes up above the phone’s body.

We can understand why the CDS-75 Deskstar exists, but thanks to its uninspiring execution we can’t get all the excited about it – not for just over £20 anyway.

Keeping fit is a tough business, especially if you live in a city where gyms are even more expensive than usual and the streets are either too dangerous or grim to run along without feeling like you shouldn’t really be there.

Often, you’ll find you just need a nudge in the right direction to get your motivation level up high enough to entice you into running along dingy backstreets.

If you’ve already got a compatible iDevice (iPhone 3GS, iPod Touch 2G/3G and iPod Nanos are all dandy) then Nike+ could be just what you’re looking for. It will help you keep track of your runs, and even track your progress online.

Nike’s standard Nike+ kit actually includes more than you’ll need if you’ve got a current 3GS iPhone. It comes with a sensor and a transmitter adaptor, but all you’ll need is the sensor, because the transmitter is already built into the 3GS. Unfortunately, iPhone 3G devices, and older ones, aren’t compatible with Nike+.

Just enable the Nike+ feature from within your settings menu and you’re good to go. Start up the app and your iPhone will begin searching for the receiver. This can initially be a bit of a flaky process but we found that once hooked up, everything ran smoothly.

Nike+ will then record your run progress – how far you’ve gone, how long you’ve been running and how many calories you’ve burnt off – and even relay your progress to you in voice form over the earphones. Other than just running free, you can also choose workouts based on time, distance or calorie goals.

A real triumph of Nike+ is just how simple it is to use. The interface is pretty and intuitive, while the mid-run display shows the basic stats of your run in an easily digestible format.

The downfall of Nike+ is how inaccurate it can be. It judges distance by working out your stride length, extrapolating the distances between the sensor, which should ideally be placed on a foot, and your iPhone. Even very small errors in this calculation are multiplied hundreds of times per run, meaning that unless your Nike+ is calibrated very well, the stats it comes up with are approximations rather than anything approaching hard facts.

Now that apps are available that use your iPhone’s GPS to track your run, Nike+ is in some ways a lesser option. However, dive into the running community that thrives around Nike+ and the accuracy issues fade away somewhat. You can upload your run data to Nike’s servers and track your progress, and then compare it with friends – or strangers – online.

While GPS tech does put Nike+ in the shade somewhat, there’s no doubting that it’s still a great and affordable way to check up on your fitness plan month-to-month.

TomTom is top of the tree for navigation, so when Apple finally put a hardware compass into the iPhone 3GS, it was only a matter of time until the SatNav giant came to the iPhone.

It wasn’t the first voice-guided SatNav arrive, as CoPilot arrived first on the App Store, but TomTom has differentiated itself with a premium quality car kit that’s designed specifically to make it easy to use the TomTom app when driving in the car, and has a few features that make it more attractive than using a generic holder.

The kit sports an ingeniously designed grip, dubbed an ‘EasyPort mount’ that only required a couple of turns to make it hold the windscreen in limpet like fashion.

This gave us the confidence that it was in no danger of dropping off and damaging the iPhone. If can be angled easily too and rotated smoothly, with the app moving between portrait and landscape modes, so making the best use of the iPhone’s screen.

The iPhone is placed inside the dock connector and gripped firmly at the top, but despite this physical connection you need to set up a Bluetooth connection to it from the iPhone, which at least is a simple task.

Once connected and the app is launched, voice directions are sent clearly over the kit’s speaker, which is louder and clearer than the iPhone itself.

On one side, you’ll find a mini USB connector that’s used for charging via your car’s 12V socket, which means your iPhone will be charged up as it directs you.

Next to this port you’ll find a 3.5mm audio out, and if you hook this up to a compatible car head unit it makes for an easy way play your iPod tunes via your car speakers. Car directions are still sent via the kit’s speaker though.

The other trick up the kit’s sleeve is that it integrates a SiRFstar III GPS chipset, which is the same GPS chip inside regular standalone TomTom devices, and an improvement on the chip inside the iPhone.

This means that is that you’ll get a stronger and therefore more accurate GPS signal that you would that just replying on the iPhone – and in our tests we could definitely discern the difference.

TomTom has also released a free Car Kit tool, that will let you read the precise GPS status from the carkit, so you can get some sense of it in action – though surely this should be built into the TomTom app itself?

The TomTom car kit is well put together, will hold your iPhone firmly and give you much better GPS reception and better audio quality than if using your iPhone without the cradle.

It would be a no brainer to recommend it then - were it not for the price. At £99, it’s just too expensive, especially in combination with the £59.99 TomTom app.

If you’ve already plumped for the iPhone TomTom app, this is a natural partner and it’s worth completing the picture with this superior car kit. However, if you’ve so far resisted the TomTom app, we’d skip both and either go for CoPilot on the iPhone or just buy a regular standalone TomTom device.

Buying a quality pair of headphones is a daunting enough experience. They tend to be expensive and hard to choose. After all, what really makes a pair of Sennheisers better than a set of Shure earphones, when you really get down to it?

It’s even worse when after buying your fancy 'phones you’re told that you really need a dedicated headphone amp to get the most out of them. Considering these amps often cost more than the headphones themselves, this revelation will often bring more fear and sadness than buyers' excitement.

One solution to this headphone buyers’ angst is the Fiio E5. It’s a headphone amplifier with a built-in battery that’s small enough to fit into any pocket. The best bit is that it costs just a fraction of the price of your average headphone amp, at a shade over £20. Shop around and you’ll find it for even less too.

A common misconception about headphone amplifiers is that their main aim is to make your music or movies louder. In fact, their main purpose is to make your audio content sound better.

While some earphones are fairly happy to be run straight off the limited amplification offered by your phone’s earphone socket, others will be left sounding dull and lifeless. The latter group will generally consist of better, more expensive headphones and earphones too. This is where the Fiio E5 can step in.

It comes with a pair of mini-jack leads to plug the E5 directly into your phone or MP3 player. Then, you just need to connect your normal earphone cable to the other end of the E5. There’s a mini-USB socket, used to charge the amp’s battery, a volume rocker, power button and the all-important bass boost switch.

We tested the E5 with a number of different earphones including the high-end Shure SE530 and Ultimate Ears Super.Fi 5 Pro sets, and the more affordable Denon AH-C452 and Skullcandy Full Metal Jacket pairs. Just as with any headphone amp, the results vary depending on the sound signature of your earphones, but we were impressed across the board. For such a cheap device, the Fiio E5 performs astoundingly well.

With the bass boost turned off, there wasn’t a huge difference in the sound of any of the earphones tested. Some demonstrated small improvements in separation, but tonally the sound remained similar to when simply plugged into the player.

However, flick the bass boost switch and things change dramatically. Even just calling it a bass boost seems a case of unfair understatement. It does increase the low-end girth, massaging the tight bass beats of the Ultimate Ears Super.Fi 5 Pro and Denon AH-C452 into something much larger, without compromising fidelity.

It also warms up the entire mid-range, expanding what audio nuts call the soundstage to make your earphones sound, well, much bigger. The Shure SE530s and Skullcandy earphones saw less of a dramatic improvement, most likely owing to their already-warm sound, but the effect remained similar. There’s an audible hiss when music’s not playing, but it’s not loud enough to encroach on your listening pleasure.

To make the deal even sweeter, the E5 is a remarkably solid little gadget, especially considering it’s built and designed in China – home to many a piece of cheap and tacky consumer electronics. Its robust metal body is wonderfully slim, while there’s also a solid clip on its back that’ll let you attach it to a piece of clothing with ease.

The Fiio E5 may not be a like-for-like replacement for a headphone amp costing more than £150, but if you’ve splashed out on a half decent pair of earphones, there’s every chance that this cheap and convenient gadget could make them sound significantly better. In short, the Fiio E5 is better than it has any right to be.

Wireless charging sounds like futuristic technology, doesn’t it? It sounds like the sort of thing that would normally be consigned to science fiction stories, sitting next to androids – and not in the phone sense – and computers that know what you’re thinking before you do.

The Powermat Portable, alongside similar devices like the Wildcharge, represents the first steps into this promised land of future technology. However, in practice it’s not quite as revolutionary as it may first appear.

For starters, it still relies on a physical connection between two solid surfaces: that of the Powermat itself and the charging surface of whatever it is that you’re juicing up. Perhaps predictably, in our tests we were trying out Apple’s iDevices with the Powermat.

For the iPod Touch and iPhone, the Powermat demands that you use a peripheral that also acts as a case for your device. From the front, the cases look much like any other, black in colour and offering a reasonable level of protection for your cherished device. There are two main ways in which they stray from your usual case design though.

Firstly, the Powermat case extends a little way beyond the actual body of your iPhone. This is because the Powermat case connects directly into your iPhone’s power socket. This we could get used to quite quickly, since it doesn’t really add that much bulk to the device, even it does mess with those carefully designed proportions a little.

Less easy to get on with is the charge panel, which lies on the back of the Powermat case. This is a hard, flat piece of metal-rimmed material – exactly what material we’re not entirely sure - but it’s what the Powermat case uses to interface with the Powermat dock itself.

This panel sticks out a few millimetres from the rest of the case, a constant reminder that this is not a normal case. It’s a reminder that we didn’t find entirely welcome either. Disrupting the smooth contouring of the iPhone, it somewhat ruins the ergonomics of this most ergonomic of devices, making it less comfortable to hold, especially if you’re using your iPhone to play games or use apps.

Thankfully, we found the actual charging powers of the Powermat to be much less disagreeable. The Powermat portable is a fold-up peripheral, made up of three separate charging plates. Put a device equipped with a Powermat case on one of them and they’ll be pulled magnetically into place and start charging automatically.

New device connections are signalled with a quick bleat from the Powermat Portable, letting you know that the connection has been made. It’s a useful feature too because if you lay your device too far from the charging point. The magnetic force won’t necessarily be strong enough to pull it into position.

Perhaps even more than its limited wireless credentials, one of our favourite features of the Powermat Portable is that it uses intelligent charging. That is, once your device is fully powered-up, charge will stop being sent to it. One way to ruin a battery’s longevity is to over-charge it, a common issue with trickle chargers frequently used with standalone rechargeable batteries.

The three charge panels work independently of each other too, so you can charge, say, a Nintendo DS, iPod Touch and BlackBerry at the same time without having to worry about doing any of them damage. Then again, even after folding up the Powermat Portable, the mat itself along with its own AC adaptor isn’t necessarily all that much smaller than three separate chargers.

The Powermat Portable does come with a number of different country adaptors, which is a very nice touch, even if we did find that the UK one tends to stick in the plug socket as you yank out the adaptor.

Plus, there’s the cost. If you’re looking to make the most of the Powermat Portable, by using three different devices, you’ll have to spend around £150, which is more than the RRP of some of the devices that the Powermat range supports.

We don’t disagree that wireless charging is a fascinating route that we hope gets explored more thoroughly over the next few years, but we’re not convinced that the Powermat Portable justifies its price in real-world terms. It’ll only save you a small amount of room if you’re using it as a travel power point and it has far too much of an effect on the aesthetics and ergonomics of the devices its used with.

Even if you’re planning on showing it off to friends, you may well be met with disappointed sighs as they realise that the Powermat Portable isn’t quite as wireless as they were hoping.

A round of applause goes to Powermat for making inroads into this interesting technology, but we don’t recommend you start saving up for this particular accessory.

Wireless charging is apparently the future. With more and more wireless charging device entering the market, it seems only natural that we should be promoting this potentially power-saving, eco friendly solution.

The Wildcharge is one such device that can charge almost any elctrical device using electromagnetic power.

We were given the iPhone case to test the product with, although there is a universal adaptor available for devices powered by mini USB or micro USB, and most handsets including Nokia and Sony Ericsson.

The Wildcharge is a mat that plugs into mains power. The rubberised iPhone case slips onto the iPhone and then the three magnetic conductors come into contact with the mat when you position it on top, completin a charging circuit.

The charger isn't the largest thing in the world - you can fit two devices on it, which makes it seem pretty pointless when you could just plug them into a power socket with a multiplier.

What would make the device more exciting would be if it was larger so you could fit more devices on it.

Another issue is that the iPhone case is chunky - not something you'd want to permanently leave on your iPhone. If you already have a case for your iPhone, you'll have to take this off first.

We can see the same issue applying to any one of the universal chargers to - for these, you have to plug the swivel arm into the charging socket of your device, and then place this onto the mat so the contacts touch the magnetic base.

The Wildcharge doesn't decrease the amount of time an item takes to charge, or use any less power than a wall charger would.

Pricing is also a deterrent. The Wildcharge mat costs £50 by itself or £60 bundled with the iPhone charging case.

If you want to charge more than one item, you'll have to shell out another £20-£35 for each additional accessory.

This seems a small fortune for something that allows you to charge two items at a time, rather than one.

Criticism aside, we can see the ease of having the Wildcharge next to your bed, so if you're one for sleeping with your phone permanently fixed to your side, you can just slap your phone onto the powermat for overnight charging.

Although Wildcharge is a great concept, it needs a little more development before we can see it taking off, and people realise the potential of wireless power.

One of the great benefits of having an iPhone is being in touch with the world of work or play wherever you are.

But while users love push email, their iPhone batteries' generally don't. Short of carrying around the charger and plugging it into a computer/plug socket at every opportunity, there's not much you can do. Or is there?

Enter the i3G Power Station. It’s not much to look at but this compact powerhouse has the potential to breathe new life into your iPhone or dock-able iPod.

This nifty rechargeable battery pack weighs in at just 6.5g with vital statistics of 60x50x10mm, meaning you can still travel very light but with the added confidence of extra battery power should you need it.

But, of course, there’s no point in carrying the i3G Power Station around with you if you haven’t actually charged it. You’ll need to do this using the USB cable that comes bundled with the iPhone and iPod.

If you want to kill two birds with one stone, you can also snap it into the end of your chosen device and charge them in unison. It simply plugs into the gadget like a wired charger, except it’s sans wires.

We plugged ours in for about two hours and it appeared to be fully tanked up and ready to go after that period. The little arrows on the front of the pack flash blue in ascending order to show you that something is happening, and when it’s had enough power, the lights stay constant.

Once unplugged, if you want to test it still has what it takes, you simply press the test button and the lights will flash again to a level indicating how much power lies within.

After that, it’s just a case of remembering to take it with you. This charger is so compact and bijoux that it is easily buried at the bottom of a bag or left on the kitchen table when the user in need is somewhere far away.

Once this little space shuttle is connected to the iPhone/iPod mothership, you get a reassuring acknowledgement that it’s doing its thing as the battery bar looks the same as it does when the device is charging.

Sounds all well and good. But what if you need to use your iPhone when out and about and it is in need of its charging buddy?

Generally speaking, you can carry on as normal as the charger is very small, but when you’re trying to answer a call quickly, there is a danger of underestimating how much length you’ve added to your device and whacking yourself around the chops. Which, we’re not ashamed to admit, we did several times.

This shouldn’t be so much a problem for the iPod as you don’t tend to put that near your face or ear, unless you’re into that kind of thing that is.

The manufacturer reckons this mobile charger provides up to an extra 250 hours and 5 hours of standby and talk time respectively, or an extra 20 hours of music playback on the iPod.

Whether that happens in reality as well as theory really does depend on what type of user you are and, if you’ve got an iPhone and are pushing emails to it like there’s no tomorrow or you’re a 24/7 music nut, for example, you may find it offers you less longevity than the average user.

Imagine the scenario - you're on the way out for the day when you grab your iPhone and to your horror realise that the the battery is nearly flat.

The Griffin Powerjolt Reserve helps you get round this as it's a charger that fits into the cigarette lighter charger point in your car.

At the back of the charger is a standard USB port and into here you plug the standard iPod cable, letting you charge your iPhone while on the road. As it's a standard USB though you're not limited to plugging in an iPhone - it will charge any USB equipped device.

Attached to the charger is a back up battery that clips on via a magnet and can be detached and plugged into the underside of your iPhone. Plug it in and your iPhone charges as if it has been plugged into the mains.

Griffin says it provides the equivalent of a full iPhone charge, enabling you to keep going when you're away from the car and this seem to be spot on in our tests.The battery is  lightweight, so while it adds length to your iPhone it won't make it too bulky and you can easily carry the reserve around in your pocket - if only for emergencies.

To quickly and easily see how much charge is left in the reserve, there's a button on the front that you press and up to five small LED's light up, depending on how much charge is remaining. When plugged into the car 12V socket, both the iPhone and the reserve are charged at the same time, and the reserve pack takes three hours to charge from empty.

The Powerjolt Reserve is compatible with all iPhones, and all of the 'old skool' iPods with hard disks. While it will charge the iPod Touch too, it's listed as only partially compatible as the pack blocks the headphone socket which is on the base of the Touch, so you won't be able to listen to music while charging.

Other downsides are that you'll need to remember to bring that cable with you in the car as without it no charging will be 'a happening and if we've being penickity it also could potentially block your gear lever depending on where your socket is located.

Finally, you do need a car - we did wish there was an adaptor so we could charge the reserve in the house too. Take note that in our eight-year old test vehicle, the 12V socket only charged devices when the key was turned in the ignition, so we couldn't leave it in the car to charge. On most vehicles though this won't be an issue.

Overall, we like the Powerjolt reserve, and if you have a car and an iPhone, it's certainly worth getting one, even if the reserve is only used as an emergency.

Most people keep their phones about their person. Right now, your phone’s probably in your pocket. It is, isn’t it?

Even if you’ve got your handset within your grasp, sometimes the idea of being able to check your watch for calls rather than rummaging around in your pocket to see who’s calling is a pleasant one.

You might be in a meeting, where the slightly impatient-looking watch move is still far better than the downright rude grasp for your phone. Or perhaps you’re in a cinema, where the tiny bit of luminescence from a watch display won’t win you those hate-filled looks that a room-illuminating phone screen would.

At the top of the range model in Sony Ericsson’s Bluetooth watch series is the MBW-200.

You’d never guess the metal-strapped watch was Bluetooth-enabled without delving into its menus or scrutinising the couple of millimetres of extra girth it has around its back.

Although it took us a while to figure out to sync the MBW-200 to the phone, primarily down to our stubborn insistence on not reading the manual, after figuring out exactly which button to press, it worked like a dream. The watch automatically searches for the nearest device so, as long as that’s your phone, all you have to do is confirm a few pop-up requests on the phone itself.

Once duly sync’d, calls and texts will cause a light vibration in the watch, and the caller’s number or name, if they’re in your phone book, will appear in the one-line LCD display. Not only is this a great application of Bluetooth functionality, but it’s certain to impress your friends too.

This would be enough to justify the MBW-200s existence, but you can also control your phone’s music player from the watch’s buttons too. The three buttons to the left of the watch’s face take on these duties. The middle one acts as a play/stop button, while the others boast dual functions. Quick taps on them change the volume on your phone while more prolonged presses change tracks.

The most impressive factor of the watch is that it manages to include all these features without ever doing so conspicuously. Aside from the small OLED display, the MBW-200 looks and feels much like a standard high quality, tasteful mens’ watch. Well, that and the fact that Sony Ericsson is written on the fascia.

Thanks to the power-draining Bluetooth features, the battery in the watch won’t last anywhere near as long as a normal watch- with a claimed 7 days of constant use- but charging it is easy enough. The MBW-200 comes supplied with a clip that attaches at one end to a pair of connectors under the watch, and a standard Sony Ericsson charger at the other. Unless you’re the kind of person that literally never takes off their watch, it shouldn’t pose a problem.

Impressed as we were with the MBW-200s Bluetooth functionality, at £199.99 it’s up against a lot of quality watches from several names that are much more renowned in the watch world than Sony Ericsson- Tissot and Rotary to name but two. Wisely, Sony Ericsson has made the designs of the three MBW-200 variants attractive but relatively unassuming.

The metal-strapped Contemporary, which we looked at, has a largely unadorned face, apart from its surface pattern. The black, leather-strapped Evening Classic is arguably even simpler. We’re a little less convinced by the italic font used on the women’s version, the Sparkling Allure, though.

The MBW-200 is arguably a lot more useful than your normal watch. It’s a remote for your media player, and a discreet way to keep up with your phone. We can imagine it quickly becoming indispensable for anyone that gets on with its Bluetooth features.

The Leyio is a portable 16GB secure storage and file-sharing device that lets you transfer data wirelessly to other Leyio owners.

It transfers data up to a maximum transfer rate of 10MB/s, with the range extending up to 10m but you have to be nearer than that to establish communication. That you do by pointing two Leyios at each other and holding down a button on both simultaneously. As well as wireless transfers, the Leyio features a detachable 2GB USB drive and a USB interface for connection to a PC.

We were initially sceptical about this bright, funky looking device. It's not exactly overburdened with extra features. You can preview pictures but you can't view video files on the tiny screen and it can't play music. It's all about storage and data transfer, but what really surprised us was how easy and fun it was to use.

Once you've paired two Leyios, all you need to do is highlight the file or folder you want to copy and flick your wrist. The device feels great to hold and vibrates when it sends or receives a file. Transfer speeds are quick and sending files is effortless, if slightly too easy to do by accident if you gesticulate when you talk.

Data stored on the Leyio is protected by a fingerprint scanner and five-digit pin code. The fingerprint scanner, like most, is a bit hit and miss but the backup pin code entry is simple.

As soon as you first turn the device on, you have to swipe your fingerprint. This is then stored and only you can access the device. If you get it wrong five times, you'll have to enter the pin code. This seems a little overkill as the Leyio is presumably designed as a bit of fun rather than a serious business tool.

Even the removable USB stick is wiped as soon as it's re-inserted into the Leyio, so there's little chance of accidentally leaving a confidential file lying around.

The fingerprint scanner doubles as a scroll wheel and select key. A second button lets you to connect to other Leyios, cancel operations and move out of folders. You can manage data on your Leyio by connecting it to a computer, where it'll show up as a storage device. You can also add links for your social networking profiles via a management tool on the website.

If everyone had a Leyio, you could just flick your phone number to the new friend you'd made, flick your electronic business card to a contact or your holiday snaps to your mum. It'd be really useful. Unfortunately, everyone doesn't have one and they cost £159 to buy.

Despite its handy features and cool design, we can't really see the Leyio catching on. How many people actually need to transfer data between themselves when out and about? We've heard some rumours about Leyios being given away in the future with contract mobiles, which could help, but we're really not sure how big the Leyio's potential market is at this price. If you still want one, you can find out more at www.leyio.com.
