New rMBP 13 256gb or rMBP 15 256gb Iris Pro

For a $300 difference is it worth getting the larger display? Besides the track pad and slightly faster RAM, is there anything the older 15" doesn't have??

15 is still better in every way, except it doesnt have the new träckpad.

IMO it depends entirely on exactly how much portability you need. If it will sit on a desk most of the day, and you don't have to carry it super far, go for the 15". To me it isn't a matter of price difference, but a matter of size (and maybe weight) difference. I went for the 13" for my lug around machine due to the size. I have a 15" that sits on my desk.

Go for the 15".

Quad core is faster and the screen real estate makes it a LOT easier to work on.

Thanks for the feedback.

I sold my iMac 27" and will be getting a separate 4K screen to connect the rMBP to it. So while at home it will be used as a "desktop" with an external display, but I will also carry it around with me but not to the point where I care about portability. I guess my question is, how far apart are the 13 and 15 inch in terms of performance?

Unless you need the portability and the battery life, the 15" is better in every way.

Smart. This is what I did last year, except my 13" rMBP doesn't drive a 4K monitor at 60Hz. If I could do it over, I'd pony up for the 15".
