Okay, this is my situation. I have Panther installed on a Mac Mini right now. Using the 'Up-to-date' program at Apple, Tiger is now being shipped to me. It will take (according to them) about 2 weeks to get here, around that. Should I wait for it to get here, then do a clean install? Or continue using my Panther, then upgrade? Also, I should let you know, I got my Mini yesterday. So I don't have much on it right now. What I really want to know is, how difficult the upgrading process would be. For instance, upgrading from Windows 98 to Windows XP is a huge pain in the ass. Is it the same situation with Mac OS X? Thanks!
