Hey guys, I'm trying to decide on a laptop and I was wondering what the real world performance is between a 13" rMBP and a 15"? I've seen benchmarks on how they compare with the 15" doing quite a bit better, but I'm wondering how this translates to real world performance. For example, how long does it take to open everyday larger programs like Outlook, or compiling code or video encoding. The size of the 13" appeals more to me, but before I make that decision I'd like to make sure I'm not giving up a lot of performance for the convenience of it being easier to carry. Thanks for any info.
