This will be my first iMac, or Mac of any kind for that matter. I'm honestly a casual PC user, not a gamer, my family will be using this iMac for homework, surfing, iMovie and iPhoto, Garageband (I'm a novice guitarist/songwriter), etc. Fairly common stuff. A few points: 1) I can't wait on the 2012/13 refresh, as my PC is pretty much dead. 2) Thinking of going with the 21.5, 2.5 Ghz model 3) I don't want to spend a fortune, as I just recently bought 2 iPads and I plan on buying the next iPhone when it comes out as well. Having said all that, I am thinking of upgrading the RAM to 8 GB and purchasing AppleCare (since this is my first Mac). Is the 8GB worth the cost? And Applecare? I should also add that I'm buying Time Capsule, and that my job has a discount program that will save me roughly $125. Pays the taxes, at least Thanks everyone. Feel free to recommend anything else. But I prefer the desktop because it'll be less abused by my kids than a laptop/notebook.
