People rush to upgrade macos the day it is released. Upgrade is cheap for em too. Oh and no need to format (yea beat that microsoft)

Trying a mac os upgrade is not a big deal, you can rollback and all works fine. Do that with windows let me know how ot goes. I never upgraded because I didn't feel like formatting I'm just lazy and if I don't like it I gota spend another day installing xp? Aaaagh.

I used it a bit it is actually quite an improvement on xp in terms of simple administration like setting up wifi and getting meaningful error messages. Not a big fan of the new start menu. Performance on 1gb of ram is attrocious. Why would they even sell it that way?
