I'm still looking at buying a 15'' powerbook, and I have a few questions that I think warrant a new thread. 1. In a previous thread, I heard about joining the Apple Student Developer Program to get a great discount. It says that they require proof of enrollment (such as a current or past class schedule). I haven't started school yet, so I don't have any schedules. What else can I use as proof of enrollment? Would my admission letter work? 2. My computer purchase will mostly be bank-rolled by my father, and he has concerns with Mac compatibility with PC. Is there anything I could present to ensure him that they're ok? He's really stubborn unless I can provide evidence in my favor. Thanks!
