Sony VAIO VGN-NW20EF/P review


A stylish machine with decent office performance, but 3D power is lacking

Good performance ; Great screen ; Good design ; Portability

3D power lacking ; Some flex in plastics

A good laptop from Sony that offers good performance and solid portability but falls a bit short on 3D prowess

Sony Vaio NW20EF/S review


The newest model in Sony's budget NW20 range is similar in design to the £750 NW11S/S model we reviewed four month ago. However, beneath the funky silver wood-grain effect is a much more modest specification. You still get Sony's attention to detail...

Sony's design and build quality is unquestionable, but a weak processor and a dull display make the NW20 less of a great deal than the price would suggest.

Good design. Looks good

Awful reliability. This is the second time I have bought a Vaio and neither have lasted two years without requiring significant hardware replacement. In this case, a new hard drive. In the case of my earlier purchase, a new screen and battery ;...
