I was so happy when my mother got me the new imac 21.5" computer for Christmas, and also got me Mac home office, Screenwriting software and the extended warranty. She spent a lot of money, and I was not expecting it. I love my computer, its super-fast and the screen is beautiful. But recently I have been reading a lot of bloggers who claim that the entry level imac is not a good decision to get because the $1499 model has better graphics (I can't tell the difference, mine look great), and more GB (1T vs 500Gb), and I guess a better processor? They're claiming that in the future with all the software updates, the entry level imac won't be a efficient. I'm so upset now because I love this computer and now I'm hearing all these people saying I should have gotten the higher end model. On top of this, many also say the 27" is the one to get since you get a gigantic screen. I think the 21.5 screen is more then big. Any advice? Should I call apple and trade them for the higher end model and spend the extra $300? Or is the model I have fine?
