The title says it all. I picked my new machine up from FedEx, got home, and upon starting up the system, nothing happened. The monitor was blank, the keyboard had no power, and it never made that chiming sound at startup like it is supposed to. I spent an hour on the phone with Apple, and they concluded that the machine is DOA, and arranged for a replacement and for me to send back the one I just got. I even hauled the heavy ass thing into the Apple store, a five minute drive from my apartment, and they concurred with the DOA diagnosis as well.
