I just ordered a 2.7ghz/16gb/256gb rMBP. I do audio production. technically for my purpose, 1680*1050 cMBP with dual drive setup should do better. because I can have faster drive config (raid0) and because the cpu needs less pixels and scaling to push to the screen. On the other hand HDMI + dual TB really seemed like a swell idea. You can drive a 27" monitor via HDMI and still have two raid0 portable setups hooked to the TB port. Which is practically impossible on the cMBP, despite having internal drive setup you are extremely limited with external configs. I also appreciate the smaller footprint since the uMBP 15" (2008) i have now with two drives is ****** heavy. Also yeah. I do like the Retina screen - guilty as charged. I'm having 2nd thoughts still. And returning is PITA here as well.
