Im going to college next month. This is my first mac so i want to have time to learn everything about it. Im not a big computer person. So i know this upgrade should have -New keyboard -Trackpad -Case( no more plastic) -better screen Those are the big things for me.. Is that worth waiting for it?? I want to have it by Aug. I want to have a lot of time with it... What do you think? Wait until Mid-Aug or the one that is out is good enough?
