Hi, I'm a recent MAC switcher--got the unibody Macbook Pro--I love it!! I was wondering if Snow Leopard will be available as an upgrade when its released. By "upgrade" I mean, like they have it for Vista; it keeps ALL your document, files, folders, etc. [I have upgraded Vista basic to Ultimate in this fashion; I've heard its also possible to do with XP] intact, but simply "upgrades" the OS. Will I have to do a fresh install for Snow Leopard? Installing MS Office, CS4, etc. again sounds kind of daunting if you ask me, lol. Thanks for the help!
