Lenovo U160 review Around the same size and price as a netbook, but more powerful and with a higher screen resolution – an excellent budget choice.

HP Pavilion dv7-4035sa review The 17in screen and high quality keyboard are tempting but there's no excuse for such poor performance or the unusable touchpad.
£600
Sony VAIO F21Z1E 3D review Hugely powerful in applications, and capable of 3D Blu-ray playback, but its graphics card is comparatively underpowered.
£1800
Samsung RV511-S01UK review Impressive core components and performance to match, but its dedicated graphics card doesn't add enough value to warrant its high price.
£579
Sony Vaio VPC-S13L9E review Just light enough to count as an ultra-portable, but with near-desktop performance, a decent display and an optical drive built in.
Toshiba Portégé R700-17W review Small and incredibly light, the R700 still has a decent display resolution, near-desktop performance, good battery life and a three-year warranty.
