I don't want to derail this thread, but the 13.3" sony vaio I now have is exactly what I was wanting. It's extremely powerful so it can play all source games on high graphics (if I wanted) and is also very light, cool and quiet. The keyboard is also one of the best I've ever used (beats my G15 hands down).

I've got Windows 7 on it now, and I'm actually considering just taking the laptop to uni instead of my stupidly big desktop PC lol.

Remember though this thread is about Mitch's monitor of win .
