Wondering about buying an iMac from Amazon or MacMall vs from Apple. If I have a problem with the computer, does it matter who I buy it from? It would be under warranty, so Apple would fix or replace no matter where I buy it, but not sure. I guess the difference is within the first 14 or 30 days, who is going to be more flexible with a return, but after that its under Apple warranty and discretion. Any thoughts?
