My new 24" 2.93 1tb iMac arrived today after ordering it March 3rd. Everything is great about it except for a cluster (like 8-10) of dead pixels in the upper right of the screen. This bugs me, so I want to the it replaced. My question is how does Apple go about replacing computers? Do I get a new one first then send back the old, so I am not with out a computer for a week? Also do I send everything back with all the accessories or just the physical computer?
