I dropped the computer off at the apple store last Wednesday. Apple store genius noticed the rattle in the screen and agreed to send off the computer for repair... only when it came back Saturday there was no repair done - Apple said it was "within specs for this model". So I asked the guy at the counter if he could hear the problem and he took it back to the workshop area behind the store, only to come back in a few minutes to say their techs couldn't believe that the folks down at the main service center didn't at least replace the screen. The apple store even opened a brand new unit in the back to compare with mine, and then also compared them with the samples on the floor. They then proceeded to offer me a brand new replacement computer right there on the spot. I took them up on the deal and am now typing this note on a newly manufactured rMB. Coconut Battery says it was made on 11/2/15, and battery is from 10/5/15.
Pretty awesome service if you ask me.
