I do love my rMBP, but it's not been without its problems. First, I had a couple of "dead pixels" from the get-got, then a new one appeared around day 3. I wasn't looking for them, they were blatantly obvious being in the middle and bright. The screen was replaced, on account of a probable defect in the glass. This was not before having to order a new screen in. Then when I dropped my laptop off I got a call 2 days later saying they didn't realise they needed to order a special repair kit (as it's new) so I waited a couple days more. When I got it back, I noticed the screws weren't fully tight, the bottom plate was squishy and eventually snagged a leg hair. When I went in again I was told one of the screws was too long/threaded so would need a replacement. Strange considering the bottom plate was perfect when I got the laptop. This meant I had to wait (again) for the screws to come in and then come in myself for repair (again) at a later date. Now I have noticed image retention. I wasn't looking for it but now I notice it all the time. Even worse, I've noticed on the actual glass of the display, there is what I can only describe as "pitting" in a horizontal line across the middle - exactly where the recess of the keyboard is below the spacebar. The marks on the glass are worrying as I think that will happen whatever I do as it's the aluminium rubbing the glass. Has anyone else noticed this? I've kept my laptop on a very padded case when I transport it but obviously it's not enough.
