So I went ahead and ordered a new 1.8 GHz i7 256GB 13" Air that arrived yesterday. It's still nicely on it's box unopened, because I'm debating if I should return it or not and wait for the fall for the new ones.
I wonder: why on Earth did you order it a few days ago if you have those doubts? I seriously don't get it how can people buy on impulse without conducting any though process...
