I have my rmbp 13 for a couple of weeks now and it's everything I expected it to be, and then some! I know people think it's a "bad deal" if you look at purely specs, but I don't hear them complaining that the pure specs of the iPhone aren't the best around.... Still a super smooth phone and a joy to use. The same thing goes for the rmbp 13 in my opinion. Look past the numbers and you'll see a quick, responsive machine with a beautiful screen. And then there's the build quality, the feel of this thing.
I also own a MBA but this thing is another level of design, keyboardfeel, rigidity. I love it
