Setting standards. Dell's former Precision M4700 maintained its top position in our workstation ranking for a year. Now its successor is available and faces extremely high expectations. We exhaustively tested whether it really can live up to them.

Fall is Apple season. One year after the iPhone 5, Apple releases its direct successor, the iPhone 5s. In terms of looks, this is not much more than a mere cosmetic update - the 4-inch IPS display and the chassis remain unchanged. There is only one notable exception, as the new home button now ships with a fingerprint sensor. More updates can be found when examining the iPhone 5s' innards: The new A7 SoC turns Apple's new flagship into one of the fastest smartphones out there. Still, is all of this sufficient to defend the top spot?

Freshly polished. Sony presents their updated Xperia Z with the latest hardware and a Full HD screen. The Japanese company's new family member has much more to offer than just a processor update, so we took a closer look for you. Read on to discover how Sony freshened up their smartphone...

Big Business. The new HP ProBook 470 promises professional quality at a bargain price, but what is the catch? Despite a Core-i7 chip, a lot of memory and a dedicated Radeon GPU, this 17-inch notebook is available at prices starting at less than 800 Euros (~$1093).

Ultrabook by Toshiba. Toshiba now has a new ultrabook series in its lineup and the manufacturer relies on cutting-edge technology for it: Haswell ULV processor, touchscreen and a swift SSD cache are to lure laptop buyers. Whether it can will be seen in our test report.

Ultra-huge. 6.4-inches, Full HD resolution and a Qualcomm Snapdragon 800. These are the impressive specs for the combination of a smartphone and a tablet. We are not concerned that the Xperia Ultra Z is not powerful enough to handle all upcoming tasks - but we are not so sure about the ergonomics. Operating the device with just one hand can be a real challenge.

Silver arrow. Toshiba sent us a 15.6-inch multimedia notebook after we already reviewed two larger 17-inch devices. How does the silver colored aluminum device perform and what can you expect from the Satellite P50-A-11L?

Light(s) in the dark. Equipped with a quad-core Haswell CPU, Nvidia's fastest mobile single GPU, and capable of various lighting effects, the Alienware 17 vies for the attention of gaming customers. Our review will determine if the update is a worthwhile choice.

Strong build with a few weaknesses. The all-around notebook of Toshiba is equipped with a powerful Intel Core i7 from the Haswell generation and a dedicated GPU from Nvidia. Plenty of RAM rounds off the packet. But can the notebook deliver what it has promised?

Short-winded. There are many affordable multimedia laptops that even manage up-to-date games in medium to high settings for around 600 Euros (~$813). Toshiba's Satellite C55-A-1D5 is no exception. However, it exhibits shortcomings in ergonomics, build and, above all, battery runtime.

Modest, fast, well-made. The XMG A503 is the newest model in Schenker Technologies' mid-range gaming series. The Ivy Bridge CPU and the GeForce GT 650M have been replaced by a combination of a Haswell CPU and a GeForce GTX 765M. Is this enough to satisfy our expectations?
