With Freeview HD, 3D, Full HD and smart TV apps all wrapped up in an edge-to-edge glass design, Toshiba's 42VL963 might appear, at first, to be an everyman TV that's in prime position for a place in the nation's living rooms.

And though Toshiba, as a brand, has a heritage in putting together irresistibly good-value packages of the latest features, the 42VL963 is a reminder to never buy a television without first having a full hands-on demo.

It may have some usability issues that we'll discover later, but this 42-inch Edge LED TV hides them well.

With the lights on, the 42VL963 is quite the looker, with a single piece of glass covering almost the entire front of the TV.

Behind is a bezel about 10mm wide that surrounds the visible panel, while its depth of 34.7mm is also quite an achievement, though this does taper out slightly at the bottom.

The Toshiba Places smart TV portal – including BBC iPlayer – makes an appearance on the 42VL963, though it's a wired affair here; there's no Wi-Fi on board.

A Freeview HD tuner features, as does one-touch USB recording, while the 42VL963's got plenty of picture-boosting processing features, too.

Movie-centric picture presets are available – 'Hollywood1' and 'Hollywood2' (the latter has a touch more contrast and the back light is turned up a tad) – alongside dedicated settings for a games console and PC.

There are also a couple of far-out choices; ColourMaster, AutoView (where the 42VL963 monitors surrounding light levels and alters the brightness levels itself), Active Backlight Control (which dynamically boosts contrast and black levels) and Active Vision (a frame interpolation tech that lends smoothness to Blu-ray discs in various strengths).

All that said, the reason to choose this particular model over others is the inclusion of a polarised panel for passive 3D – with 3D specs in the box reaching the magic number of four; families rejoice.

The 42VL963 is accompanied by the 47-inch Toshiba 47VL963 and 55-inch Toshiba 55VL963 in the VL Series.

Those after an active shutter 3D alternative should head for Toshiba's otherwise-identical TL9 Series, which stars the 40-inch Toshiba 40TL963 and 46-inch Toshiba 46TL963.

Review: Raspberry Pi 512MB

Supremely affordableLots of interfacing optionsAlmost 100% open sourceMassive communityMany example projectsNo VGA connectivityLack of decent starter guideTricky to installModest CPU performanceNo ARMv6 Flash support

The humble Raspberry Pi came to life as little more than a prototype in late 2011, knocking around some trade-fairs. But even at this point, it had been in development for over four years.

The brainchild of Eben Upton, who started piecing together the Pi on the longest piece of breadboard he could buy from Maplin, its principal motivation was to make computing accessible, with a plan to give the boards to school kids in the hope they'd get enthusiastic about hacking on the devices, just as the Raspberry Pi's founders had done with their home computers in the 80s.

It was this 80s computing meme, along with co-conspirator David Braben's address book famously plundered for contacts and the idea that programming should be taught to everyone, that has helped the Raspberry Pi get phenomenal traction.

Just a few months after those prototypes were shown at trade shows, over 200,000 people registered their interest for the first 'Model B' boards, 20 times the capacity of the first production run, and the rest is history.

The Raspberry Pi sold half a million units in 6 months, not into the educational market it was designed to revolutionise, but into a wide demographic of hackers, makers and tinkerers.

Pi config

This is a device that can legitimately be described as a fully-fledged PC, albeit one that's embedded into a diminutive printed circuit board, measuring just 85.60 mm by 53.98 mm. The CPU isn't powerful, an ARMv6 running by default at 700Mhz, but it can be powered by a USB cable, and even batteries, and is capable of running a graphical environment with accelerated video - through either an HDMI port or a composite RCA jack suitable for televisions.

The lack of old-style VGA is a problem when you consider there are now so many old redundant monitors, but this oversight is more likely to be a limitation of the SoC hardware than a shortfall in design.

Either way, the Pi's killer feature isn't the hardware specification, it's the price. The Raspberry Pi can be yours, delivered, for around £25 - and that includes 20% UK VAT.

Pi memory

The demand has been such that the cheaper 'no networking' Model A has yet to be released.
But in the short time that the Model B has been available, there have been 3 revisions. The first two, marked revisions 2 and 3 when you check the processor identifier, differ only by the removal of a D14 component, originally situated beneath the HDMI port, and some fuse modifications.

But the third update, officially called 'Revision 2.0' and available from the end of September, packs more significant updates, despite looking almost identical to previous versions. The 'almost' refers mostly to the additional two mounting holes, which should make it easier to attach your Pi to a case or anything else, and a supplementary 'P5' header, consisting power, ground and 4 additional connections to add to the array of GPIO ports.

The biggest improvement is the amount of RAM. This doubles, from 256MB to 512MB whilst keeping the price the same, making the Raspberry Pi much more feasible for running desktop applications. On our system, a default boot to the command line left us with 384.4 MB free, rather than a measly 126 MB on the first model.

The general purpose pins have also been tweaked, reversing those used for I2C, a widely used data bus system. GPIO is where the Raspberry Pi overlaps with other projects like the Arduino, because it allows the user to build their own hardware and hook it up to both digital and analog signals managed from software running on the Raspberry Pi. The advantage with the Pi, of course, it that you can run a full operating system on the hardware, rather than bytecode.

The official operating system is a Debian-derived Linux distribution called 'Raspbian'. This too has changed little over the months, and while we've been able to successfully install the system onto a 2GB SD Card, you'll have a better experience with more storage, as you'll have more freedom to add your own files.

If you've used the command-line on a Debian-based distribution before, such as Ubuntu, you shouldn't have any problems as many of the same commands and configuration options will be familiar. But even if you've only ever used Windows, the command line isn't that difficult. Arm yourself with a couple of tutorials and start investigating. If you break the installation, the worst that can happen is you'll need to reflash your storage with a new version of the distribution.

Review: Updated: Lenovo IdeaPad Yoga

Superior quality IPS displayTransforms into a tablet…and moreTop-notch keyboard (for typing)Surprisingly affordableSnappy performanceNo backlit keyboardTouch response is inconsistentAverage battery lifeNot fast enough for gamingLacks 1080 screen

As far as Windows 8 devices go, we're having a hard time seeing any other first-gen Windows 8 system or device being more interesting than Lenovo's 13-inch IdeaPad Yoga. It's attractive, snappy, versatile, and surprisingly affordable.

Microsoft's Surface runs a very-close second in our book. And, just like the Surface, the 13-inch Yoga validates the Windows 8 operating system in a way that the OS itself can't quite accomplish.

More on this in a bit. Let's start from the top.

Lenovo IdeaPad Yoga review

Technically speaking, the Yoga is an Ultrabook, primarily because it meets Intel's "Chief River" Ultrabook specification:

Intel Ivy Bridge CPUHas dimensions of 13.1" x 8.9" x 0.67"Can resume from hibernation in 7 seconds or underHas USB 3.0 and/or ThunderboltAt least 5 hours of battery life

Even though Lenovo assigns the Yoga to the category of convertible Ultrabook, the manner in which it converts into a tablet and back is unlike any other.

A special patented double hinge allows the keyboard to flip 360 degrees, all the way to beneath the display. The hinge also allows a few other positions. In all, there are four different ways you can set it up: standard laptop mode, tablet mode, tent mode, and stand mode.

These modes aren't just hype; while testing the Yoga, we consistently used three of the four modes throughout the day. Tablet mode while sitting in front of the TV. Stand mode while using it as a second screen. Laptop mode at tables and desks - as well as when inspiration struck while sitting in front of the TV or anywhere else.

The tent mode seems like the least usable, although Lenovo makes the point that this is a perfect position for cooking.

Review: Kobo Mini

If you'd rather not travel with a high-end tablet and think that even a Kindle is too big to carry on the daily commute, the touchscreen Kobo Mini could be the e-reader for you.

At a mere five inches across the diagonal, it's the tiniest e-reader we've seen since the Sony Reader Digital Book PRS-300, though it's not the slimmest.

At just a centimetre (0.4 inches) in depth, the Kobo Mini is relatively bulky, though we can't argue that it's too heavy for long-term travel; at 130g (4.73oz) it's a mere slip of a gadget.

Kobo Mini review

And slip it we did, into a variety of bags, pockets and briefcases, though this is one e-reader that you should keep close to your body; we managed to house it in jeans, as well as some shirt pockets, though the advisable addition of a protective case could seriously interrupt that.

Perhaps just as important as size for anyone after an e-reader to take on a business trip, commute or picnic is battery life.

The Kobo Mini uses an e-ink screen - though a rather low resolution version, at just 800 x 600 pixels - that negates the need to pack a charger, with battery life rated at about two weeks.

Kobo Mini review

That's with its built-in Wi-Fi de-activated, which you'll probably forget to do.

This Canadian-designed e-reader is, on the inside, identical to the latest generation of Kobo e-readers, including the Kobo Glo and Kobo Arc.

Kobo Mini review

But priced at £59.99/AU$99.99/US$79.99, it's considerably cheaper than its bigger specced brothers, as well as rivals such as the Kindle Fire, the Nook Simple Touch and even the cheapest Amazon e-reader, the Kindle.

Kobo's online e-book shop is accessible from the Kobo Mini, while other new features of the refreshed operating system include both Reading Life (which monitors your progress), Shelf (folders that can be created to house specific books and documents), and a book wish list on the Kobo store.

Kobo Mini review

Frequent travellers without the time to stock up on books before setting off to the airport might mourn the lack of 3G connectivity on the Kobo Mini, but it's a pointless spec too far for most.

Who really needs to be able to download a book anywhere, anytime? Not anyone with more than two books on their device, that's for sure. Besides, the Kobo Mini can store about 1,000 e-books.

Kobo Mini review

That lack of 3G and non-book-related apps of course help to keep the cost down to a mere fraction of the price of an iPad Mini, Microsoft Surface, Samsung Glaxy Note or other top tablets.

Fashionistas with low horizons should know that 'SnapBacks' in red, purple and teal can be bought from Kobo and swapped-out for the default grey cover.

Design-wise the Kobo Mini is nothing special; it comes in either black or white, each sporting a silicone outer layer that's easy to grip in one hand.

Review: Scythe Katana 4

Small footprintDecent performance considering sizePoor mounting arrangementNot as good as a larger cooler

Fans 120mm and larger dominate the enthusiast and overclocking market. What hope, then, for the plucky little Scythe Katana 4 and its 92mm fan?

Scythe is an experienced outfit and this is the fourth version of the compact Katana, so if it doesn't deliver, it's probably time for the towel-tossing to begin.

As before, the latest Katana is smaller than your average high performance cooler in just about all directions, measuring nearly 100mm square and 143mm in height.

The upshot of this is that you're unlikely to find a remotely mainstream ATX motherboard or case that won't jive with the Katana 4.It's not going to tussle for space with your RAM or argue with your graphics card.

Scythe has also tried to improve cooling performance via an increase in the overall cooling area provided by the aluminium fin stack while maintaining the triple copper heat pipes of its predecessor. What you make of the results will depend on your expectations.

If you're looking to equal the performance and noise levels of a larger 120mm cooler, it ain't gonna happen. Even so, at stock clocks, it's a nice cooler that keeps peak operating temps around 50°C, which is far from shabby.

That said, we're less keen on the mounting arrangement, which involves those ghastly press-in clips in conjunction with Intel boards (except LGA 2011 boards). We've never been confident they deliver even force across the surface of the CPU package.

Review: Motorola Droid Razr HD

The Droid Razr line has fast become the new flagship for Motorola, and with good reason. Last year's Droid Razr and Droid Razr Maxx were strong smartphone contenders, with impressive battery life and slick screens. Now, exclusively for Verizon's 4G LTE network, the Droid Razr lineup has been refreshed again, with bumped up hardware and edge-to-edge displays that earn that HD moniker.

The Droid Razr HD shares the Kevlar backing and AMOLED screen of its predecessor, but of course the resolution has been bumped up to a modern 1280 x 720 resolution. The phone itself has also gotten a bit thinner.

Droid Razr HD review

It also bears many similarities to its Droid Razr siblings, Motorola's Droid Razr M and Droid Razr Maxx HD. All three phones run a 1.5Ghz processor with 1GB of RAM. The Droid Razr HD is in the middle of the M and the Maxx HD for storage and battery life, but it's no mid-range device. Motorola has also promised an Android 4.1: Jelly Bean upgrade for all three new Droids.

And speaking of Droids, with so much talk about Star Wars in the news lately, we can't help but mention that Motorola actually pays royalties to Lucasfilm to use the name Droid. George Lucas is nothing if not an excellent businessman.

So is the Droid Razr HD worthy of name? It's certainly no bumbling C3PO, it's as handsome and helpful as R2D2, but is it a stone cold robotic killer like IG-88? Can it assassinate the competition from phones like the iPhone 5, Galaxy S3 and HTC One X+? Let's find out.

As the name would suggest, the Droid Razr HD is a sharp instrument. Thanks to a thin body, it looks the part of a premium device in either black or white. Picking it up you'll notice it's a little on the heavy side, weighing in at 146 g (5.15 oz).

Droid Razr HD review

Holding the phone, the Kevlar backing is pleasant to the touch. The feeling is somewhere between very soft plastic and firm rubber. It's a lot like the rubberized rear chassis of the HTC Windows Phone 8X.

The pattern is unique, sort of a mix between herringbone and hounds tooth. It's extremely smooth but grippy enough as not to be slippery. An edge-to-edge screen and tight, thin bezel give the Droid Razr HD a seamless design. At 131.9 x 67.9 x 8.4 mm (5.19 x 2.67 x 0.33 in), it's tall and thin in a way that resembles the Galaxy S3.

Droid Razr HD review

The display is 4.7-inches long, the same as the Droid Razr Maxx HD, and a little bigger than the 4.3-inches of visual real estate on the Droid Razr M. It's a big screen, those with smaller hands will find it takes a little shifting around to reach from top to bottom.

The Razr HD has three capacitive Android buttons: back, home and recent applications. Directly below them is a logo for Verizon, the exclusive carrier for the three new Droid Razrs.

Droid Razr HD review

Motorola slapped its name at the top of the device, directly above a notification light that flashes when you've got a missed called, email or text message.

Droid Razr HD review

On the right side you'll find the phone's only physical buttons. The lock button is towards the top, it has a ridgey-ness that feels a bit like a nail file, but not harsh. The volume rocker is below it, in the middle of the right side. It has little metal beads at both ends that make it easy to find with your thumb.

Droid Razr HD review

Located on the left side is a pair of ports, micro-USB for charging and data connections, and HDMI for connecting the Razr HD to a television or monitor. Just above the ports is the phone's micro-SD and micro SIM tray. Like on a late model iPhone, it pops open when you insert a paperclip or SIM tool (included) in the small hole.

Droid Razr HD review

A solo external speaker is found on the back, to the right of the camera lens. Laying the phone flat on its back will not completely muffle audio, but it does reduce sound quality.

Droid Razr HD review

Motorola claims a "splash resistant" coating on the Droid Razr HD. The phone can't be submerged in water, but it's implied that it will stand up to rain or an errant glass of water. We did not put this to the test, though, and consumers should know that the one-year warranty against defects does not cover liquid damage.

The Droid Razr HD is a bit bigger than the Droid Razr M, getting more battery life, storage space and a larger, higher resolution screen in exchange for its heftier form factor and weight. The Droid Razr Maxx HD, however, is the thickest and heaviest of the three, thanks to more storage and a huge 3300-mAh battery life.

The Razr HD's microSD option makes the Maxx HD's higher GB count somewhat negligible, and the HD already has great battery life with a 2530 mAh cell, as we'll get into later. Consumers who want something easier to carry (and afford) will likely find the Razr HD to be a balanced offering.

Size-wise, the Droid Razr HD is in the middle of svelte smartphones like the iPhone 5 and brick-like devices such as the Optimus G. It's sleek but not terribly thin, and also rather hefty. You won't forget that it's in your pocket, but it's certainly not in cumbersome phablet territory like the recent LG Intuition.

Overall, the Droid Razr HD achieves a premium feel. The big edge-to-edge display gives it a smooth, simple face that's a pleasure to touch. The Kevlar backing is resilient and grippy, and the only other phones that feel like it are HTC's Windows Phone 8S and 8X.

Users with small hands that want something they can nimbly navigate might prefer a Droid Razr M or iPhone 5, but for those that want a bigger handset with serious battery life, the Razr HD is a solid choice.

Review: Scan 3XS Graphite LG5

We're living in the post-Ultrabook era. Even when laptops are designed to do something much more taxing than pushing websites around, we still expect them to be sexy.

Which explains why this diminutive laptop has us in two minds. On one hand it's a tiny machine that packs a decent punch on the hardware side of things. On the other, it's a little on the ugly side due to its thickness and drab colouring.

It's also surprisingly heavy for its size. It's not an Ultrabook, in other words. The 3XS Graphite LG5 isn't looking to make a name for itself with its aesthetics - it's about what's inside that small, if not quite svelte, chassis.

Designed from the core up as an 'ultra-portable' gaming laptop, this packs a punch where it matters the most - the processor and graphics. The Intel Core i5 3210M is a dual-core, four-thread 22nm Ivy Bridge processor running at 2.5GHz. This is a capable workhorse of a chip that will handle all the games you throw at it, and chew through more serious work as well.

While the Core i5 is a great option for any modern laptop, it's in the graphics department that Scan is hoping to separate this machine from the droves. The 2GB GeForce GTX 640M is a more than capable offering, especially in the context of this screen.

Here we have an 11.6-inch TN panel, boasting a native resolution of 1,366 x 768 pixels. We'll admit that isn't a lot of room in Windows, and the TN viewing angles don't make things easy here either, but in gaming terms this pairing really excels.

Unlike some of Nvidia's mobile GPUs, what we have here is a genuine Kepler chip - the 28nm GK107. This GPU runs at a healthy 835MHz and boasts a pair of SMX modules, equating to 384 CUDA cores. Indeed, so powerful is this GPU that it's only in the memory department that we see a difference between this and the theoretically more powerful 660M found in PC Specialist's Optimus IV.

The main news to take away from this GPU is that you can hit great frame-rates at the native resolution with a minimal amount of tweaking, if any is needed at all.

This machine is all about gaming performance. The pairing of the 650M with a relatively low-resolution screen equates to very healthy frame rates.

The important upshot of all of this is that we have a laptop that can play the latest titles at medium-to-high settings very smoothly. There may be more powerful machines out there, but you'd be hard pushed to match the gaming prowess for anything like the cash.

DirectX 11 gaming performance
Max Payne 3: Frames per second: Higher is better

PC SPECIALIST OPTIMUS IV: 25
SCAN 3XS GRAPHITE LG5: 34

DirectX 11 gaming performance
Sleeping Dogs: Frames per second: Higher is better

PC SPECIALIST OPTIMUS IV: 19.2
SCAN 3XS GRAPHITE LG5: 28.3

DirectX 11 tessellation performance
Heaven 3.0: Frames per second: Higher is better

PC SPECIALIST OPTIMUS IV: 15.2
SCAN 3XS GRAPHITE LG5: 18.1

The storage side of things is a little less convincing, because while you'll find a Corsair Force 3 SSD keeping things speedy, at just 120GB there's not a lot of room for the OS and the many games you'll want to throw on it. We'd recommend going for a 240GB drive for an extra £64 using Scan's system configuration tool.

The final key part of the specification is the 8GB of DDR3 1,600MHz RAM, providing plenty of room to work and play in.

Overall, this Scan laptop is a bit of a mixed bag. The SSD is too small, but easily rectified online. The undersized screen isn't as easy to fix though, and we'd advise anyone looking to do work to look elsewhere.

However, as a gaming system there's a lot to love here. The strong graphics performance and low native resolution equate to fast framerates without having to wind the settings down.
