I loved my little 13" Aluminum Unibody. Mine was the first model...no Pro. It was amazing; configured to top of the line and it served me well. A buyer came along and made an offer "I couldn't refuse". That was the easy decision, the hard part was trying to decide what to replace it with. After many a sleepless night I decided to go ahead and get the 13" MacBook Air (June 2012). It's sleek, elegant, weightless and meets all my expectations and more. The only bad experience I have had with it was spending 1½ hours on the phone with Apple support asking a question about "Remote Disk" only to find that the representative had no idea what that particular function was for. (I want his Genius T-Shirt) So, to get to the point... I'd like to hear about your experiences with your MacBook Air... how you use yours, if you have any issues, any tips you may have or things to look out for, what specs you chose, etc.
