Those are all really great points.
About virtualization, we've actually finished P2V on all our client servers about a year ago except a select few and it's been beautiful. We're rolling out virtual desktop 'cloud' and that'll get even better as we get more people on it. I'm picturing a day when we're never restoring system images, but reverting snapshots. Even minor fixes may be as simple as reverting a snapshot to an hour ago... or whatever.
This basically will make Windows desktop OS's pointless. I really see your point there. Thank you.
Update: I just installed Ubuntu on a VM. This is very mac styled. I do really like it so far.
