I need to transfer - well, actually, copy - the data on my mini to my new 12" PB. I recall being told that it could be done with firewire, but I can't remember how . . . And is there any reason I can't upgrade the OS to the same one I have on the mini? Can I just do that using firewire? (I do have the install discs, if I need them.) Okay, I'll start by plugging it in . . .
