I did the sorta the same Wrote code for 4 years on 13" Air, switched to a 15" MBP (with dedicated GPU). Satisfied. For me, the size or weight of the laptop isn't relevant. It's the "clumsyness of it". With unibody Apple made the larger ones easier to move around. I'd buy a 17" MBP if they would still make them. I prefer laptops to an external monitor because I use the touchpad with gestures a lot, and I like the focus.
