I'm upgrading from a 2011 air because it only has 2gb of ram and performance has suffered a bit. Because I get a student discount the air and pro are about the same price. The configuration I'm looking at is the 2.4ghz i5, 256gb ssd. I'm not sure if I should go with 16gb of ram or AppleCare. They are within 10$ price wise. I like the piece of mind with AppleCare but am nervous about not maxing the ram. Currently I use about 3 gb if ram at a time. I'm leaning towards AppleCare but am open to suggestions.
