I have the decked out current model 2.66 pro 13 inch and i think the hard drive makes it move slow. I primarily use outlook 2011, safari, firefox, uploading lots of high def pics, and chat. I have a friend who can can get me the stock models of the Air at a good discount, meaning I cant custom order with 4gb and it is a huge difference is why I would get the 2gb air but do I have major issues to worry about having 2gb from the 4 im using now?
