I got a new pc a few weeks ago and got Windows Vista along with the pc. If I compare Vista and Xp there isn't really a big difference, besides the look. I've been told Vista is more safer, so if your pc gets infected by a virus it doesn't have a change to spread out throhough your whole pc.. I'm sure the ones who create virusses will find something for this someday. Btw, I have the basic version, better versions will have some more features. Worth the money? I'd say no.
