I still do not see how my Vista Premium can be the only perfect running Vista in use world wide.
Only problem I ever had with it was the same problem I had with XP: optimizing search, which I figured out was a bit different from XP to Vista.
Vista is a beautiful, fast OS, at least on this Toshiba Satellite; I will never cover it with Windows 7 or any other OS, although I do swap out hard drives to fool around with various Linux distributions and now Windows 7.
Windows 7 beta seems to be a bit "lighter" than Vista, comparitively.. maybe a bit faster, hard to tell (have not done any benchmarks, etc).
I'll buy Windows 7 but it'll be put on a spare hard drive; Vista stays (for as long as it's supported).
