Assuming you did not get your rmbp back yet, could you report if they were able to fix the problem, if you do? Would be great, thanks.
I think its weird, that they put that under "accepted manufacturing limits". I paid 2500.- dollars + apple care, they send me a product which behaves not as intended and if I want it to get replaced, they won't do that... Expected more to tell the truth. Of course its a minor issue, compared to ghosting etc. but nevertheless it bothers me, because the machine doesn't feel as strong and robust as those machines without this problem do. I feel like they should replace it if I want that / if it's necessary.
