I've used Vista, and it might not be bad per say, but I just don't like the way it uses ram. It keeps it in constant use with it's Super <font color=red>censored</font>, or whatever it's called, when it's not even using it, which sounds to me like a great way to wear out RAM. Also, every computer I've used that has it has run slow
Vista states it's requirements and recommended specs. You wouldn't blame the autobahn for your crappy honda going slow. Vista runs fine on my rig, and it's well over a year old.
