Jeremiah said:you can't tell me vista is running fine with just 512mb. maybe i say MAYBE when your browing just arround vista but open up winamp or media player whatever, browse the internet while downloading something and have messengers running will be no fun at all i say...
and playing an modern game or at least a game came out the last years will also be no fun since vista will pull too much performance for itself...
win XP professionell sp2 corparate IS the better choice fo a system like that. don't let yourself be fooled by the shiney new look of vista and the "easy feeling" of it.
just get a download a tool for vista aero look to xp or something, looks same - needs less perormance. i think one of em is called vystal or something.
