I too am staying far away from Vista until SP1 at least. I have zero reason to upgrade - fancy UI - pfffffttt, who cares about eye candy - performance increase? Don't make me laugh. Improved security? I have zero security issues with XP.
I tell clients to just say no to Vista.
Ditto
I figure it will be done being beta tested by the public and patched all to heck (ala winME) in about two years.....then maybe ill give it another spin....
