This whole Vista to Windows 7 reminded me of the old WinME to Win2k public beta test.
While I hate Vista with the fiery passion of the sun, Windows 7 is growing on me. Although, I don't use it personally (yet) when I have to work on one it is a much more pleasant experience.
What is it about Vista that people hate? I personally hated it, until I used it

I find it runs as fast as XP and has a few extra features that are beneficial to me. I do have a new laptop with Windows 7 on it and I've got to say, I was going to dual boot Windows and Linux but there is no need since Windows 7 basically ripped off the look of Xwindows (*nix version of Windows).
