Make new from old - it is possible with external graphics cards. Once a laptop gets old, you can upgrade RAM and sometimes even the CPU, but it is only rarely possible to replace the graphics card.

Quiet and frugal. HP only charges around 260 Euros (~$358) for the Compaq 15-h024sg. For this price you get a simple 15.6-inch notebook with a frugal AMD APU and a 500 GB hard drive. The Windows operating system is not provided. Our review shows if the notebook can still convince us despite the low price.

Unique and suave. It will likely be the last smartphone that Motorola makes under Google's authority. The Moto X offers a few extraordinary features and rather conservative looks. Can Motorola score with it a last time?

Flexible. Lenovo tries to make using a touchscreen easier for the users of the IdeaPad Flex 15D with an opening angle of up to 300 degrees. We indeed liked this solution. Our test uncovers whether the device is also convincing beyond this feature.

Redundant successor? Samsung launched an entry-level tablet on the market that did not really convince us in several fields with its Galaxy Tab 3 7.0. Now, 7 months later, we have our hands on the Lite version - is it a sensible diet or simply nip/tuck madness?

Ultimate rush. Which tech specs does the technically savvy user find most compelling? A beefy CPU, lightning-fast SSD, and a potent graphics card propel an Ultrabook to the top of the "must-have" list. Does the Zenbook UX302 score a "Very Good" this time around?

More business. Solid office companions are very popular, despite the tablet and ultrabook boom. Can the ProBook 640 continue the tradition of sturdy and efficient business devices?

Haswell update. The combination of a high-performance Core i7 quad-core processor, matte screen, and Windows 7/8 Professional already indicates that the ProBook 450 G1 wants to be a work machine. HP aims at both professional and private users at the same time. However, the company demands just under 800 Euros (~$1099) for the laptop. Our test report reveals whether the device is worth the money.

Slimming mania. The review sample's big brother completely convinced us in the editorial office. Users who were looking forward to a comparable version with a dual-SIM feature will, however, be disappointed. The South Korean manufacturer has slimmed down the tech specs to such an extent that neither smartphone has much in common apart from the screen size and name.

Understatement with security. Reliability and security are probably the two most important things for business users. This should also apply for their notebooks, and Dell's Latitude series earned a good reputation. The Dell Latitude E6440 wants to continue this tradition – our review shows the strengths and weaknesses of the new model.

Quick convertible. Sony has come up with an innovative construction that allows converting a laptop into a tablet quickly. Besides the review sample's unusually high resolution of 2880x1620 pixels, particularly its size of 15.5 inches stands out, as that is actually incompatible with its use as a portable tablet.
