Got a brand new BTO rMBP13" and low and behold it had image retention. The screen looked washed out right away. I noticed when I was updating it, and it had to restart and I saw gray outlines in the login window. I then ran the image retention test with the checkerboard and bam, that confirmed it. The computer has already been sent back for a full refund. I told the Apple guy on the phone this is ridiculous that they still do this sine June 2012. He just kept apologizing. I did not figure out which screen it was. But its absolutely ridiculous the third generation retina macbook pros still have these problems. I know not all of them do, but damn. Maybe Apple should have kept the entire classic line. Pathetic.
