Sony Vaio P small light laptop

Sony's new tiny Vaio P laptop might not be as cheap as some of its rivals, but it packs an impressive specification that more than makes up for the price difference.

It weighs just 638g but packs a high resolution 8in LED backlight screen that stretches to 1,600x768 pixels.

There's a 1.6GHz Intel Atom chip inside and 2GB of RAM, plus 128GB solid state hard drive. It also features built in 3G, so you can get online wherever there's mobile phone coverage.

The Vaio P will be available in February from £849, see Sony for further details.
