Ahh "debris" in between the display and the keyboard / main body area. The problem is there is always debris, there is debris in the air we breath, there is particulate everywhere. So what exactly constitutes an acceptable amount of debris. No one would accept a human hair in between the screen and the body cracking the display... That would be crazy and happen all too frequently. yet we all know that leaving a pencil in there and closing the display is pretty much assuring death for this display. The problem is that middle ground... If apple makes the tolerances for their display too small in the quest to be "THIN" then normal airborne debris can become a problem. The display is covered in glass too... something quite a few laptop makers do not do and prefer a matte finish. They all contribute... personally I am not a huge fan of the laminate display but I can't argue with the appearance. I am thinking of people that live near mining, coastlines and other areas where larger particles in the air are a distinct possibility. one grain of sand happens to work its way in there and CRACK. question is, is that really a manufacturing problem? or something totally different. I am sure that apple tests these products in clean environments.... which may taint their testing.
