Sony joins the ultraportable contest with a simply gorgeous mini-laptop. Mattew Sparkes finds out if it has enough to compete with the MacBook Air and Lenovo X300.

Sony Vaio VGN-TZ31MN


Lightweight, portable, fast, good colour and definition on the screen and good battery life

Power button in a funny place, could do with a lid locking mechanism.
