Notes On Setting Up A New Mac
Good points by Neven Mrgan, but I especially agree with this one:
Apple IDs and MobileMe accounts need to become connected. I should be able to enter one and have the other pulled in automatically. It’s kind of really weird that the whole setup process skips MobileMe - you have to go into System Preferences to add it yourself.
It’s weird, and it’s one of the things I hope Apple will address in Lion.
