MacBook Pro with retina display received the largest price cut. They also upgraded the processors on a couple of models. I'm thinking of upgrading to a 13 inch retina MacBook Pro. Retina display and longer battery life are the two things I miss on my 13-inch MacBook Air.
The cheapest retina MacBook Pro now retails for $1499 in the Apple online store. Thats much less than I payed for the Air last year.
