vista sucks... you need an extremely high-in-resource machine to actually run it, and even so sucks up a lot of your ram and graphics...
I prefer XP SP2, thank you, though I actually prefer Unix. But then again, almost no games have compatibility with Unix, so I must use Windows...
Besides, Vista asks questions about everything. Like when you put in a CD, it actually asks you if you wanna open it... Why the hell would I put a cd in if I didn´t want to open it? |_|
Anyways, I suppose upgrading in a near future is unavoidable
