Facelift. HTC re-engineered their One X, packing their current top model, the One X+, with a few more horsepower and a bigger tank under the hood. But those aren't the only renovations. A run on our rugged test track shows what else is inside and how the revisions have altered the device.

High-priced Ultrabook. HP integrates Thunderbolt technology, a FullHD touchscreen, and a fast solid state disk into a premium Ultrabook made from aluminum, magnesium, and glass. The latest in technology doesn't come cheap though: the Spectre XT TouchSmart retails for 1600 Euros (~$2150). Is the high price really justified?

Head-to-head. Being more expensive is not always better, and successors are sometimes worse. HP and Asus confirm this truism with the EliteBook Folio 9470m and the Touch-Zenbook UX31A. Who offers the best laptop for the lowest price? This question arose in the Office and Multimedia category.

Dithering escort. In December Archos announced the market launch of the Archos 97 Titanium HD tablet. Now the latest scion of Archos' Element Series is available and promises pictures in razor-sharp HD quality. But can the smart "Frenchman" really compete with the equally sized, 9.7-inch Apple iPad 4 Retina powerhouse? Or will the tablet escort get cold feet after all?

Marathon Tablet. After Asus, Microsoft and Samsung, the spotlight now shines on Dell's Windows RT tablet PC. The XPS 10 proves to be a long-lasting performer which makes traditional notebooks look outdated, especially in terms of battery life. However, the offered performance comes at a high price.

Endurance machine. An Intel ULV processor fused with a solid state drive and a high-capacity battery adds up to a swift, enduring ultrabook on paper. Our review reveals whether this is true and shows the Xirios S402's strengths and weaknesses.

Horror cubed? Almost two years after the last installment, EA releases the third game of the Dead Space series to horror fans. The nightmarish third-person title will attract players with a well thought out co-op mode and a diverse crafting system. We tested the single-player mode for several hours and have determined the hardware requirements.

Business premium. The Dell Latitude belongs to the high-end business class and must meet the especially high standards of quality, functionality and expandability. Most professional users expect a good display, an adequate performance and solid mobility. Our detailed review will show whether the current Dell Latitude E6530 is up to the task at hand.

The golden mean. With its Inspiron 15R-5521, Dell shows a rather unusual combination of energy-saving ULV processor and dedicated middle class GPU. The efficient components do not only indicate a moderate energy demand, but also a long battery life. We have tested the top-class model with AMD's brand new Radeon HD 8730M.

The compatible one. No matter whether iOS, Android or Windows RT, all operating systems have their quirks when it comes to the compatibility with the standard Windows 7 or Windows 8 versions. Asus' VivoTab Smart might eliminate these restrictions owing to Intel's Atom CPU and Windows 8. We exhaustively tested how well this works.

LTE for 430 Euro (~$590). The One SV is the newest member in HTC's portfolio and it's designed to shake up the hotly contested mid-range smartphone market. We look at how well the new 4.3-inch smartphone with its updated hardware, LTE support, and integrated card reader handle our battery of tests.

Cool and quiet. A Pentium processor, a 320 GB hard drive and a DOS operating system make for an inexpensive office notebook priced at around 330 Euros (~$441). Our review shows whether Asus produced a good notebook at a low price or tried to pinch pennies in the wrong places.

Ultra-Hybrid. Toshiba presents quite a few interesting Ultrabooks to the world. Our latest test model is a fusion of a tablet and Ultrabook. It employs a 12.5-inch touchscreen and a power-saving Intel Core i5-3317U processor with integrated Intel HD Graphics 4000 IGP. The Hybrid model looks great but what does it have to offer on the hardware side?

Expensive office notebook. A Core i5-processor, a matte display and Windows 7 Pro should result in a simple working device with proper performance. However, Asus wants 650 to 700 Euros (~$870 to $937) for the notebook. Our review shows if it is worth the price or if Asus has an expensive shelf warmer in its product range.

All in white and ready to entertain. A pretty design, a bit of gaming, and a bargain price - that's a quick summary of the Packard Bell Easynote LV44HC-137GE. How the white multimedia notebook stacks up is the subject of this review.

Slow start. December 2012 was led by the search engine giant Google. The beginning of the New Year was however a bit quieter. Tablets from some low-cost suppliers found their way to our test lab and presented very mixed results. January was themed "midrange" for smartphones.

Portfolio expansion. Sony is currently launching a torrent of new Xperia models on the market in order to satisfy all conceivable target groups. How will the 4-inch midrange model, featuring a clock rate of 1 GHz and a 512 MB working memory, fare in our tests and is the RRP of 239 Euros (~$323) reasonable?

Ultra-Touchbook. Few laptops of 2012 impressed us as much as the premium Ultrabook from Asus. The model achieved a rare 90%. Everything was perfect - even the display maintained a high standard. Will the touch panel make this great model even better?

Runtime miracle. HP launches a slim Windows 8 tablet on the market, which mutates to a full-blown laptop via the keyboard dock, dubbed Envy x2 11. An energy-efficient Atom SoC from Intel not only ensures exceptional battery runtimes, but also modest computing power.

Company data is especially sensitive. Business people are eager to find effective security solutions. Simple password protection is often not enough. Perhaps you've heard of some of the technologies offered as solutions, like TPM, Smartcards or Anti-Theft. But what exactly is behind them? This article explains.

Inexpensive Portégé. HP has the EliteBook, Dell the Latitude, Lenovo the ThinkPad T-Series and Toshiba has the Portégé. After the ultrabook companion Z930 we review the thicker R930 with the same form factor. A bargain for 777 Euros (~$1051)?

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?
