"....yeah, if you use your Mac for movies, games and professional photo manipulation - but for most users, it's overkill..." - an Apple Store sales clerk in Toronto describing the advantages (and the significant price hike between Air and MacBook) of a retina screen.

Oh, and get to maintain all those ports you've grown used to on your old Pro - especially useful if you need to plug into someone else's technology.
