I purchased a new 24" iMac yesterday and I got 1 gig with it and went and got 4gig of ram for 110.00 why does Apple charge 400.00 for 4gb when you can buy it for as low as $89.00. They should be ashamed of them selves. I can not believe the difference when working with pictures . Also Burning dvds is blazing fast. Is there brands of ram that are better than others. Also this imac takes notebook memory . so this is the same memory that is in the macbook pro?
