Thanks for the info. I code and also use the machine for laying out documents, web browser, and lightweight design, etc. Mostly coding. I'm normally desk-bound, however, and am weighing the value of the Retina screen if I'm going to spend most of my time looking at an external monitor. I have, however, not heard a bad review of the 15"r.
I'm surprised to learn the machines are not RAM upgradeable. That's a major negative.

Between that, the glued-in batteries, the on-board storage, and the lack of an optical drive (i.e. a slot for a second hard drive), I'm really put off the new retina MacBooks.
