I used to use a 13" MBP but my work supplies 15" MBP's. Now that I have been on this machine for a while I can't go back. I have tried on my old machine and my wife's and really like the bigger screen. With the MBP's the extra size really isnt a big deal because they are so light and thin. And with the 15" you can get a MUCH better dual graphics setup which helps with all the other non-coding things you might want to do (gaming). TBH you probably done need the power you will get, but it is nice to have. Another anecdote: a friend of mine just picked up a 15" MBP after having a 15" dell for ever. He loves it and was amazed that he could actually run Photoshop without closing other things. And if you have to do any graphics like that the extra space of the retina 15" is really good.
