There really is no reason to go with the Air unless you get the bottom model. Once you add more ram and increase the disk you're in Pro territory without Retina. I'm amazed how little battery the pro uses. I can leave the plug at home....unless I'm going to Nans. She loves the Apple butt plug.
you know dick...
The air smokes the MBP in battery life. I upgraded the Air I bought Cindy as much as possible and yeah it's fast and in the pro territory, but it's still thinner/lighter (what she wanted) and the battery outlasts my MBP by a long shot.
now go sit down.
