The return of the old master. What can be improved in an almost perfect notebook? Lenovo might have thought that it is better not to change too much and launched an only slightly revised edition of the T440s with the ThinkPad T450s. At least, the manufacturer (partly) answered the complaints about the predecessor's unusual five-button ClickPad.

No compromises - part 2. Compact, highly mobile, attractive - this is how one could sum up the Dell XPS 13. Thanks to its Core i7 processor, the notebook is quite powerful as well, although the battery life suffers as a result.

Working on details. Lenovo's ThinkPad T450s steps in big shoes. The expectations are high that the successor of the overall successful T440s is even a bit better. In fact, the T450s proves to be a carefully matured perfectionist - and it now challenges the competition from HP, Dell & co.

No (big) experiments. Lenovo only introduces small changes for the latest sibling of the X200-series – but just those changes improve a good subnotebook and result in an even better one. The manufacturer even listened to the criticism about the unpopular 5-button ClickPad of the predecessor.

Slimline. How much flatter does it get? The Core M is at its best, with 12 millimeters in an airless case. The performance lags behind the Haswell competitors, and the Zenbook inspires no wonder in terms of battery life. Still, input devices, workmanship, emissions, and (last but not least) the price argue in favor of purchase.

No more fans. Core-M makes it possible: The new ThinkPad Helix 2 is available without a fan for the first time, but is still supposed to provide sufficient performance for all important applications. Can the versatile convertible meet the high expectations of business customers?

Refusal to compromise… You can’t have it all—or can you? Dell’s latest XPS 13 pushes the envelope in a number of different critical categories, but most notably portability: this is the smallest 13.3-inch notebook we’ve reviewed. Could we be witnessing the best ultraportable to date?

Quality for little money? Asus wants to put the competition under pressure with affordable business laptops and equips its new 14-inch flagship with the currently fastest ULV processor, plenty of working memory, and a swift SSD to accomplish that. We will reveal why it is nevertheless not enough for first place in the category.

Deceptive. Slim and good-looking business laptops are possible nowadays. The non-glare touchscreen of Fujitsu's Lifebook U574 is rare, though. Is it only smoke and mirrors or a solid business subnotebook that meets all fundamental criteria?

Surprise from the second row. Asus wants to attack the established business competition with its new 12.5-inch subnotebook. The AsusPro BU201LA can not only impress with its great Full HD display, but also with an excellent keyboard and a solid build quality – and all that for a surprisingly low price. What is the catch?

Performance goes up, energy consumption goes down? After a several-month delay, Intel has finally released the fifth incarnation of their "Core" architecture, codenamed Broadwell. It's even coming on the market this year -- at least in a few machines. Initially, the new, extremely low-energy Core M series will only be used in the improved 14 nm manufacturing process. Is it a dream come true? Can we now expect to see high-performance, passively cooled Windows tablets?

Symbiosis. A powerful notebook does not have to be bulky and loud if it can also be dignified, subtle and quiet. Why pretentious and not understated? Asus thinks it knows what wealthy customers want and creates an Ultrabook that combines performance and elegance in a simple yet sophisticated chassis. Can this symbiosis really set new records in every category, just as Asus promises?

Alluring. Asus aims at tech enthusiasts with its new 15-inch Zenbook generation. The flat aluminum unibody houses a standard-voltage i7 processor paired with an upper middle-class Nvidia graphics card. The highlight of this model seems to be the 4K panel. It offers high resolutions, great colors, high contrast and wide viewing angles. Is this the winner?

Brillant. Acer's smallest convertible is now available with a Full-HD display. The price difference is only 30 Euro (~$37) and seems to be well worth it. But is the battery life is shorter than before and how fast is the new CPU? In our review, we try to answer both questions and take a detailed look at the display as well.

Weary business tablet. More than one year ago, we tested a Windows 8 tablet made by Fujitsu, which - among other things thanks to its keyboard dock - was supposed to appeal to business customers. Now, its successor has arrived - but unfortunately, not all changes are for the better.
