I just sold my air and decided to pay the difference (at least I have the 10% off movers coupon and doing the Best Buy sale). I loved my air but after having retina on my iPad air 2 and 6 plus the screen was this thing that always bothered me in the back of my mind sometimes. It's tough to go back after you have retina. I start graduate school to get my Master's this June. I am going to get Apple Care on it and keep this at least until I graduate. I couldn't be more excited! Will I notice any improvements in just every day tasks speed wise? My air was already lightning fast. Also, what is the best way to reset this Air to factory settings before the buyer picks it up?
