MB Pro Retina 13" or MB Air for mostly Front-End dev? Occasional RoR

Hi All,

I am debating back and forth between the MB Pro Retina 13" i5, and the MB Air 13"(Air upgraded to i7 and 8GB ram). Any suggestions? I will note that the retina display is not overly important to me. It is nice, however. And I like the fact that the Air is light for travel/commuting. Tough call. Thanks for the input!
