Lenovo launches a 15-inch device that fulfills its duty stoically, but cannot really stand out in any aspect. The cheap-looking casing is not particularly stable, the gaps are uneven. Pride of ownership does not evolve. The input devices are disappointing: Neither the keyboard nor the touchpad satisfy us. While we can still work fairly well with the pad's cramped keys, the keyboard provides a highly spongy feedback. Such an inferior keyboard is rarely installed in a laptop. We also count the Seagate hard drive as a negative, as in practice, it needs excessively long time to load.

Lenovo does a proper job in thermals. The components run at their normal performance limits at low temperatures (Turbo utilized and stable). The B50 always remains relatively cool, and is not unduly loud under stress. Unfortunately, the fan is not disabled even during prolonged idle periods.

The B50 with the Radeon R5 is not suitable for gaming. Current games are usually only playable in low details. The matte Full HD resolution cannot show its beauty even if the TN screen offers a feasible contrast and homogeneous illumination. However, it regrettably also displays a visible bluish tint (pre-calibration). The TFT is virtually useless outdoors due to its low brightness, which is dimmed even further in battery mode.

The B50 thus does not have many advantages, and not even its price of just below 680 Euros (~$761) is luring. The limited gaming suitability and poor build (chassis, input devices) are simply unattractive at this price.

This would look different in a 350 Euros (~$390) configuration based on the same chassis. Thus, we point to multimedia contenders with better input devices, and some with better screens and stronger graphics cards. 

First to be named are Acer's Aspire V Nitro VN7-571G (Core i5, GTX 850M) and Aspire E5-571G (Core i5, 840M). The latter does not even cost 600 Euros (~$672). The same is true of HP's Pavilion 17-g054ng (AMD A-Series A10-8700P) with considerably more gaming power (R8 M365DX). HP's 355 G2 (A-Series A8-6410) does not feature Full HD, but it comes with almost equal (low) graphics performance for 350 Euros (~$390).

Nota: si tratta di una recensione breve, con alcune sezioni non tradotte, per la versione integrale in inglese guardate qui.
