I'm curious if the Feb 2013 15.4-inch MacBook Pro 2.7GHz Quad-core Intel i7 with Retina Display was a good computer? Any issues with the display or anything else for that matter that I should be aware of? I'm looking at one that has 16GB memory and 512GB Flash Storage. Primary use will be for photo editing using Lightroom and Photoshop, surfing the web, playing pandora. Will not be playing any games. Anything I should look for or be aware of? I currently have a late 2011 MBP 13" but is too small of screen and not enough memory with only 4GB. Many thanks!
