Glad you found the right computer for you but just in case someone would like to read the review of someone who went the other way I'll state my experience. I received a new MacBook Pro at work and I had a 2012 model. This new model is easily the best laptop I've ever owned. I don't really use the retina display but you can scale the screen to 1920 x 1200 which is very useful for me because I like to use Eclipse/WebStorm with two editors open. The SSD is the big difference though - the time it takes to boot from sleep and write files has dramatically decreased. But most importantly, for me, it's no longer like having a furnace in your lap. It's very quiet and cool. I believe it's a combination of the SSD and the processor but I can now run Eclipse, WebStorm, Photoshop and VMWare in Unity mode without feeling the computer slowly turning to a halt. In fact, I don't even notice a drop in performance with those and about a dozen other lighter weight apps open.
Anyway, that's my experience...
