We just upped from XP Pro to Win 7 Premium on several systems, including our portables. Truthfully... we love it, and didn't think we would.
We never used Vista - in fact when a new system arrived with Vista, we bricked it and reloaded XP. So I can't compare the two.
other than the faster start-up time
I can't recall the last time we reached over and shut them off! They run 24x7... connected to surge and UPS systems just in case, but we never turn them off.
