I am using a Lenovo X230T laptop with a 12.5" IPS (1366x768) screen that has pretty accurate colors and crazy good viewing angles, for my photo editing needs. I'd like to transition over to a 13" MBP and have heard the screens are pretty accurate for photo editing as well. Screen resolution will be similar but how accurate are the colors? I had a 13" NON-Retina MBP back in 2010 but I wasn't doing any editing on it. I do recall the viewing angles were pretty good being a non-IPS screen. I'm more concerned about losing colors and contrast. Thanks.
