I never noticed burn in on my first rmbp at first, but it was there alright and started to bother me. I was past the exchange period but decided to get another rmbp in the hopes of getting the so-called "superior" Samsung screen. Luckily I got a Samsung screen second time around and it exhibits no burn-in. Had I gotten another LG with the issue I would have just returned it and stopped there. So I was just wondering, are people still desperately exchanging their rmbps with LG screens for the rmbps with Samsung displays, going through 3, 4, sometimes 5 computers? I can't imagine going through the hassle. Now I have to sell my other rmbp with the LG screen but I think it was worth it for one attempt and a better display on a computer I will keep for a while. What did all of you do about the dreaded LG/Samsung display issue?
