I've had the DVD from MSDN for week or do, I *MIGHT* dual boot this on my laptop for development purposes, maybe.
note: This beta is not ready for daily desktop use, there are still too many performance issues and bugs to run it daily. Unless you're a developer looking to write some stuff to take advantage of vista features (WinFX, etc), or have run Beta OS's before and know what to expect, don't expect too much.
