I've been using the Windows 7 beta and it's incredible. No random Vista slowdowns, User Account Control works just right, and everything worked out of the box. And I love the new task bar. Since it's a new installation (on a better computer, too) it seems even faster than XP and even OS X. So now that many of you have had experience with the beta, do you think the final product will be enough to make you switch back to Windows? And if you've been a Mac user all your life, will you cross to the "dark" side? I'm definitely tempted.
