I have a mid-2012. I did have the IR ghosting issue with my screen, but Apple fixed that at no cost and havent had any problems since.
I use mine for some steam games like counterstrike and garrys mod, parallels to load up windows and use solidworks (or sometimes windows only steam games, like DW8), and the general stuff - itunes, iphoto, ibooks, and safari.
I love the power of the 15" rMBP, but my gaming has since gone down. And I hate having a powerful mac just for the windows usage. I will probably be getting the 12" MBA, or the next 13" rMBP as my next computer.
