Is it possible to exchange my iMac for one of the newer models? I got it in January. I would really like to have those better graphics. Here are the specs for it, I don't know if they're needed or not. It's in perfect condition, too. 21.5" 8 GB RAM Intel Core 2 Duo @ 3.06 GHz NVIDIA GeForce 9400m (blech!!!!) *Restocking fees and all that are not a problem. I'd like to get it for the better processor and graphics. *And selling it to buy a new one is way too much work.
