Actually this will probably be the last one for Vista. They pretty much ironed out what was needed. If Vista ran the way it does now when it was released I think it would have been much more accepted.
Dobt it, XP itself got SP3
How lon has it been since SP1? a year max, and already we are at sp2, wow vista is so lame and buggy and vunerable
if you feel so, then dont use it.
Using any OS or even updating it is totally your choice.
No duh, but I am just saying
And are you sure there is a service pack update, cause if there was there would be word of it on the microsoft home page
