Its pretty good, I just wish MS would give us a way to log issues. (not talking about the beta feedback software since its not beta...)
I still can't believe VS doesn't really work - should have been fixed long before release ...
Here are the issues I've found - all running Vista supplied drivers so don't blame those

1. A 5 hour extended battery now only lasts 50 minutes ...
2. As above power management just doesn't work, screen never turns off etc.
3. Sound just works - the lineout doesn't - never worked on RC either.
4. It runs super hot but doesn't hang ... yet

5. No games work, the video driver gets me a 3.5 with Aero but reports a generic back to games so they won't load.
6. My desktop icons continously re-arrange themselves, no matter how I have it setup.
7. Returning from (Locked) takes minutes sometimes ... ? eh ...
Virtual PC Beta has been my life saver
