I function poorly without sleep. I try to keep a minimum of seven hours of sleep to feel at least decent and able to operate optimally. Any less, and I feel the effects of it (and if I sleep only seven hours for a long time, with lesser quantities here and there, it really hurts me).
I'm of the opinion that if you have XP, there is no reason to upgrade to Vista. If you are getting a new computer, however, might as well get Vista.
So I have McAfee VirusScan Enterprise 8.5i, and it works great - I think. I get it for free from my university.
