haha you're so evil Bernie!
Anyway, I found
this article on switching to Mac OS X I read it and it all seems pretty true.
Also once you get your beautiful MacBook check out
this thread (Must Have Software) for some programs you may want to use. Tons of great programs for you new MacBook!
Anyway, good luck on switching!
P.S. If you are thinking of getting a Windows Vista PC then be prepared to have 1 gig of ram set aside just for the OS!!!! I had 1024MB of ram used while running the OS, Windows Live! Messenger, and Firefox.
