I am a very happy owner of a 15" rMPB. What a great machine for my needs. So why is it I look at the new MBAs and lust after the latest, greatest version of this machine? Of course this is really nothing new. I've bounced back and forth between the Air and the larger laptop a couple of times. This time I'm sticking with the rMBP. Really, I am... Nothing going to change my mind... Damn you Apple.
