I am in the market for a new computer. I have a 8 yr old Dell and it is slow and way out of date. I am switching over to Apple because I don't want another Windows PC and for the fact it will link up with my Iphone and Ipad with great ease. I am leaning toward a 13"Pro. Is the air better or just a glorified Ipad? I do know the Pro is faster and has more memory than the Air. What are you opinions?
