Quick question along these lines ... if I buy online or on the phone, and say the computer is god forbid DOA, I take it I can only return by mail? What if it needs service in 6 months? Surely I can at least take it to the Apple store for service later on, right? The nearest Apple store is about 3 hours away from me. I won't be living in Pittsburgh until August, right now I'm at home in boonies with no Apple store nearby. Thanks for the answers.
