Ditto on the VM, this time.
I jumped right on the HD install for both Vista and 7 betas, right to the final releases, never experienced an issue, yes, even with Vista, guess I was lucky.
I enjoy running Vista from time to time (gotta keep'm updated), despite all the negativity about it, I think it's much better than XP and of course, 7 is better all around than both.
There's also the possibility of 8 being a total flop, we'll have to wait and see.
