Well, right now I have a 20 2.4ghz that is a week old. Ordered three days before the release of the new ones. I can get the 2009 "20' for 1150 and the 2008 for 1150. I can also get a 24 for 1300. But to be quite honest the 24 I really dont want because of my desk is a two tier desk. The 20 2.4 I have now I have to look up at a little as it is and it is literally two feet away from my face. I have 1600 to spend. (My wife is a accountant ). The 2009 model is upgradeable to 8gb and has DDR3, a weaker graphics card but I don't play games, plus a extra usb port. The 2008 has a better graphics card, DDR2 and is not upgradeable. What am I missing here?
