Well first I ask, what do you want to do with the laptop? And second, I'd advise you get the Air as the Retina technology in the MacBook Pro with Retina Display in my opinion isn't fully "there yet" not to say the MacBook Pro with Retina Display is a bad laptop, because its not, but I'd defiantly advise to wait at least two generations for the MacBook Pro with Retina Display to be more developed before getting it. The price will be significantly lowered then.

Though it is not one of your options, I would recommend the Regular Macbook. It comes with more features and it has much better battery performance. You can buy yourself an SSD and 8gb ram and get the same performance as the retina. Retina is great but not many things utilize its high resolution.
Out of your choices though I would say the Macbook Air. I assume this is for regular computing, in which it will be great enough for your needs. If you need to do any rendering or designs or whatnot definitely get the macbook pro.
