I change operating systems when I change computers "if I have to".
My computer still runs great for what I use it for.
My personal belief is a computer runs best for the os it is designed for, for example my system is fairly large and fast for the xp pro I'm using but for Vista it would be "small and slow".
My kids both have Vista and I have set up their computers for them. I wouldn't mind Vista, they have no problems, I'm just not gonna change for the sake of change.
