So, I purchased the 13" rmbp and had it for two days. The resolution just seemed too small for me. So, I took it back and bought the monster size 15" rmbp. For me, I hate the size for portability reasons. However!!! The speed, graphics card, and performance are STELLAR! I am NOT a 'power-user' but the speed is immense with just basic tasks! So what am I getting at? If you are considering buying a 13rmbp WAIT! The price of $1999 for a dual core vs. the quad core is RIDICULOUS!
