Rematch. More than half a year ago, Nvidia and AMD introduced their mobile 28 nm GPUs. The battle of the two top models was especially interesting. We recheck the performance with up-to-date drivers. Is the GeForce GTX 680M still marginally faster? Or does the HD 7970M perform better this time?

Cool worker. Matte display, Core i3 processor, ExpressCard slot, two operating systems - the Fujitsu LifeBook A512 is a work notebook that should please both home and business users. Our review reveals its strengths and weaknesses.

Slimmed down business. As the only Ultrabook thus far to satisfy a multitude of standardized military reliability tests, the build quality of the 6430u is sure to meet the needs of practically every business user out there. Though powerful on the outside, is its internal performance up to par?

A real bargain. Acer launched a real bargain at CES 2013 in Las Vegas. The manufacturer promised the visitors a 7-inch tablet featuring decent performance and a high-quality build. And this for a mere 120 Euros (~$160). Acer is trying to steal the march on the first wave of cheap tablets coming to the market.

Flat beauty. The VivoBook U38DT is a 13-inch subnotebook that is powered by a Trinity processor and the brand new Radeon HD 8550M from AMD. The ultra-thin construction and the precious metal ensure a very nice look. Is it worth the 800 Euros (~$1092)?

Light and cheap, but gaming capable? Acer combine a frugal ULV processor and a GeForce GPU in a slim case. This could result in a mobile, light, gaming capable notebook. Our review reveals to what extent this is true.

Business man with AMD furnishings. For those who prefer AMD processors and are looking for a reserved yet elegantly designed device for the workplace, HP has something to offer - namely the ProBook 4545s. HP wants the 15.6-inch device with an integrated Radeon graphics card, Windows 8 Pro and good speakers to gain points for home use as well.

Inspiring. Ultrabooks have found their way into Dell's Inspiron family. The all-rounders of the past now benefit from lower weight and longer battery life, in addition to the good performance. We examine whether the ultrabook measures up to the broad multimedia class.

Compact business. Full connectivity, almost 8 hours of battery runtime, perfect input feedback and a noble aluminum-magnesium chassis. A challenge for the Lenovo ThinkPad X1 Carbon and the gathered premium ultrabooks?

Surprise candidate. Lenovo again ventures into the highly competitive gaming sector with the IdeaPad Y500. The UltraBay technology enables the 15-incher to be equipped with an optical drive, a second GPU, an auxiliary fan or another hard disk. A thrilling concept that lets the laptop stand out from the competition. We exhaustively tested the SLI alternative.

Ultranetbook? Thin like an Ultrabook, yet as affordable as a netbook - that must have been Asus' goal when developing this 11.6-inch subnotebook. We will need to see if the low price point of 350 Euro (~$470) allows Asus to pack enough performance into the 21.7 millimeter (0.85 inches) thick chassis.

Totally twisted. The Fujitsu LifeBook T902 is an old school convertible and tries to combine the benefits of tablets and notebooks. A new case, updated technology and a classical business orientation are connected with high expectations for the performance, quality and the features. Our in-depth review shows how well that turned out.

Colorful midrange. After Nokia has seemingly assumed a leading role in developing smartphones featuring Microsoft's latest Windows Phone 8 operating system, the Finnish manufacturer suits the action to the word through the second model following the Lumia 920. A timeless design meets a decent camera and numerous proprietary apps in the Lumia 820. The manufacturer demands 499 Euros (~$667, RRP) for its new midrange device.

Good performance. MSI's latest 14-inch laptop is to be a mobile and powerful companion. The potent Core i5 processor aside a weight of 2.4 kg underpins this statement. Our review reveals whether MSI's CR41 is compelling.

Entry-level Windows. A dual-core processor, 512 MB RAM and a 4-inch screen for 260 Euros (~$346). In cooperation with HTC Microsoft tries to pull smartphone users away from the Android and iOS camp. But is Windows Phone 8 with weaker hardware still fast enough and competitive?

Cheap and light. First of all many ultrabooks are expensive. But Toshiba use a simple plastic case for the Satellite U940 and equip the 14-inch laptop with attractive components including a Core i5 and a dedicated SSD cache.

Smartphone? Tablet? Camera? With the Galaxy Camera, Samsung puts a product on the market in a form no one's ever seen before. Just classifying the product isn't easy: From the front it looks like a camera, from the back more like a smartphone.

Gaming cost-cutter. The CX61 from MSI targets those users who are looking for an affordable multimedia notebook - but don't want to sacrifice the ability to play games. For less than 600 Euros (~$800), the notebook comes equipped with a Core i5-3210M and a dedicated Nvidia GPU - and some drawbacks as far as build quality is concerned.

Welcome to the world of tiny high-resolution screens. Acer makes a move into the premium ultrabook market with the introduction of a 11-inch ultrabook with a wonderful 1080p touchscreen that wows. This will be an evaluation of the first attempt by Acer which brings beautiful construction elements to the masses with the Aspire S7-191.

Mirror, mirror... HP's Envy m6-1101sg is a multimedia laptop equipped with Windows 8 for 800 Euros (~$1063). An eye-catcher is certainly the keyboard's backlight. However, the screen has major problems with sunlight.

Finale. Smart convertibles, surprising ultrabooks, business classics, slim gaming laptops and a crippled Power-Radeon. We complete the year 2012 with 31 assorted reviews.

Premium tablet?At least that's the segment in which Samsung places its new 750 Euro (~$980) ATIV. Windows RT, a 10.1-inch screen, 2 GB RAM, a fast 1.5 GHz SoC from Qualcomm, and the latest wireless technologies make a solid starting point.
