Interesting review of the release candidate preview for the Windows Vista Service Pack 1 being released to about 15,000 testers and MSDN members. Improvements are performance, compatibility, and stability. Projected release date is Q1 2008 and a public preview planned prior.

Hands-On with Windows Vista Service Pack 1

Windows Vista SP1 preview released

I have not see but 1 blue screen in Vista in 18 months of heavy use (knock on wood). I do use a 8gig USB thumb drive to take advantage of the performance benefit of Windows Vista feature ReadyBoost which is nice. There will not be any statements on official support by Autodesk until the Service Pack is officially finalized and released as things can and do change between pre-release and final.
