Installation is a lot better comparing to experience of using VPC in Vista. It was a lot faster, smoother and without tricks here and there.
I am running a 30-days evaluation version of Fusion 1.1.3 The upgrade was also done pretty smoothly and quickly. My speakers were working under Ubuntu and my hardware wasn't complaining.
The only thing that I found not working so far is the scroll wheel of the mouse, this great tip fixed that.
