I've got a pretty similar story only I think mine is worse. Similar problems to yours plus a ghosting defective LG display. I am now getting the 4th logic board put in (3rd repair). They've flatly refused to replace it or refund me. I am about 9 weeks into the Apple nightmare. The worst part is that these are widespread issues it seems: http://9to5mac.com/2013/03/20/macbook-pro-with-retina-display-problems-in-every-dimension/
