So I'm in a quandary. I bought a 2013 13" MBA w/ i5, 8 gig RAM, and 256 SDD the first week of September. Now I've always loved the Retina Display, but I needed the battery life of the Air. Now with the new rMBP, it has alleviated that issue, battery life too short. So here's my question, should I try and sell my Air, and if so how much do you think I could get for it? It's barely 2 months old with only 25 batt. cycles on it considering.
