I understand that given the number of computers sold it is probable that a few people will end up going through multiple bad computers. However, my personal experience was that 5 out of the 5 rMBPs I owned had bad screens or some other problem (namely buzzing noises). The only way I could get a good rMBP was to swap the perfect screen from the buzzing model to a non-buzzing model.
I also inspected two rMPBs at my local apple retailer. The screens had issues there too. One had a dead/stuck pixel(s) and another had blue-green blotches on the screen. So, really 7 out of 7 I saw had issues.
I'm no statistician but my personal experience is certainly evidence (albeit defeasible) that Apple's QC aint great. If the number of rMPBs with QC issues is very low, what I experienced should be very improbable, and it's not just me who's having these issues as evidenced by this forum. So, I must conclude that if you buy a new rMBP, there is a decent chance that you will end up with one with issues. I agree though that the chances are going to be much lower than what the data on this forum would seem to show.
