IMO, Retina is mostly useful if your job is creating Retina enabled assets for iOS devices. Personally I would recommend a maxed out air over a MBP. I do iOS development, web development and music production on a 3 year old MBA. That said, I was disappointed there wasn't a retina MBA. It may be worth waiting to see if the fabled MBA-looking MBP comes out at the end of the year.
