I recently bought a Mid 2013 MacBook Air 13" The Specs are Intel Core i7 1.7 GHz, 8GB Ram, 512GB SSD. I got it for $950 Delivered. Came with box, charger, and original receipt. Still has AppleCare tell Sep 26, 2014. I am assuming this was a great deal no? I was looking for a Retina MacBook Pro 13" and found this. Would it be a good deal to trade this for a Late 2013 Retina MacBook Pro 13" 8GB Ram and 256GB SSD? I would be losing SSD Space but gaining the retina screen.
