Should I get Windows XP, Vista or Windows 7?

[TEF]

Only ignorant fools who can't use a computer correctly believe Vista is shit. I've had Vista on this computer since I got it back in August of 2008 and I've yet to have a problem with it (aside from a few little worms that were immediately owned by my antivirus).

I'd say use what you have, man. Don't spend any extra money if you don't have it.
