Since Windows 7 is built off of Vista it acts like a working OS, even in beta. Vista was a mess because it was a complete revamp of nearly everything. I have been using the beta since it became available and have been running my computer nearly 24/7. All my programs that I use on a daily basis are installed and every game that was installed on Vista has been reinstalled on 7 with no incident. I see no reason to go back to Vista just because it is a retail product. 7 is noticeably fatser, provides a much faster workflow once you start using the Superbar, Jump Lists, improved Navigation Pane,etc.. I even get to take benefit from the protection UAC gives now that it has become less annoying (by a huge margin), I keep Windows Defender on, as well as Windows Firewall. I have no AV installed or third party security software so if something does come along I will be able to test Windows' own ability to protect itself, the only thing that protects it alongside Windows is my routers' firewall. Even the relatively useless Flip 3D has been made faster so that I can utilize Switcher2 to emulate OSX Expose perfectly with no delay. Unless Vista SP2 plans to introduce anything fun into Vista, I plan to stay with 7.
