Damn, Vista security is much much enhanced. Everytime you try to install something, remove something, write over something, their USer Account COntrol and persmission deal whatever pops up asking you, "Are you sure?" It can be disabled, but I don't install stuff on it like everyday, lol. I just leave it.
As for Vista being slow, if you meet Microsoft's recommended system requirements, there should be no performance issues with Vista. There are some glitches here and there but it's always the case when anything new comes out from Microsoft's Window. Just get the latest drivers, or let Windows install their own inluded drivers. Then you're all set.
*Fact: Microsoft Window's Blue Screen of Death vs Computerforums.org's White Screen of Death. Which is worse?
