Typewriter with hardware weakness. The Acer TravelMate P255-M improves upon its predecessor TravelMate P253-M in several areas. A comfortable keyboard, a ULV Core i5 CPU, and an appealing design raise the expectations. In what key areas the P255-M is a solid notebook and where it loses some ground is the subject of our review.

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.

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.

Constant performance. OCZ promises the Vector 150 is a Solid State Drive whose performance remains high even after intensive use. We tested a 120 GB and a 240 GB model to see how well this works.

Now featuring Haswell. HP's ProBook 470 is an office laptop for both the private and professional field. Its price range of approx. 700 Euros (~$959) and the installed hardware also make the device interesting for users who want to replace their desktop PC at home with a 17.3-inch laptop. Our test report reveals whether the laptop is convincing.

Experiment.. The 2013 edition of the X1 Carbon came pretty close to a rating of "very good". Still, Lenovo has not stopped improving its premium ultrabook series, adding a WQHD IPS panel to the 13-inch device while also improving its battery life and implementing new input devices / ports. Is this enough to eradicate the few remaining issues?

Good, but overpriced. The Travelmate P455-M is aimed at business professionals and as such equipped with TPM, a fingerprint scanner, and security software. A ULV Core i5 processor powers the notebook. How does the system, which sells for a fairly steep 840 Euro (~$1150), handle the daily workload?

Improved by Haswell. A notebook that you carry around all the time should be as light as possible, but also sturdy and enduring at the same time. Lenovo tries to meet these requirements with the ultrabooks of the ThinkPad S-series. We review the ThinkPad S540, the current 15.6-inch model from the series. The biggest improvement: The S540 models are equipped with Haswell processors.
