I was surprised when I opened my one month old retina mbp 13" to find several dead pixels. I brought it to Apple and they said they "normally don't fix this under warranty" and that it was my fault because something must have gotten caught between the keyboard and screen when I closed it. Although, I have been taking very good care of my laptop and do not recall finding anything wedged between the screen. I just wanted to get a third opinion. My fault or faulty screen? And, are the retina screens very fragile?
