Sunray
Its sunny somewhere.
My last work laptop came with Vista installed on it, though I mainly used Ubuntu as my OS on it. Vista seemed to occupy a massive portion of my RAM just to run, and even on a fresh install with 2 gigs of RAM seemed pretty sluggish
If I get a choice, next time, I'd probably get it dual-booting with Ubuntu / XP.
I suspect something like a graphic card issue making it slow.
Heavy memory use is because Vista, unlike XP caches lots of stuff to improve performance, but it can drop it quite if it needs. Headline

" thing - wow, well done, good job 
It's decided to fuck itself up though so I've got to reinstall, but I don't have a DVD and all the pirate ones I can find are hacked.
