Had the cMBP 13, sold it due to screen resolution being so poor, purchased both 13 and 15 rMBP (due to the terrible 13 inch reviews, which having owned one I think are unjustified). The 15 is the perfect desktop replacement, it is awesome, I cannot recommend one highly BUT for me the 15 isnt a portable machine and I can't justify having that amount of money in a laptop - £1530 at discount prices is something in hindsight I'm not comfortable with.
So I'm going rMBP 13. I've tested them side by side over 10 days - the 15 and the 13, thrown everything at them and honestly I can't see a difference in the applications I use barring 2 things: Video encode (Dual vs Quad was obvious) and Rendering a simple model (56 minutes vs 23 minutes). The cream on the 15 is having the highest resolution 1920 x 1200, is that worth the extra £330 and the extra speed, not really as I don't play games on the laptop and also I can pick up a very good monitor and still have change.
In terms of web and software quirks of retina, it's first gen, it is par for the course. Once you have read on a retina screen for a week or so, going back is difficult - I'm also struggling with an iPad Mini (recent purchase for added portability) vs iPad 4 (Sold due to iPad mini form factor).
