To my horror I just noticed 2 cracks developing at the corner of the rectangular cut out just above the hindge. The plastic is cracking already and my M4 is a top of the line custom configured unit that's only 1 month old. I've babied this unit since day 1 and can't believe this is happening. Also flakes of dirt are starting tto appear underneath the screen glass. So I can't get rid of these annoying dirt specks. I am really disappointed. Toshiba has to fix this cause I paid top dollar for this machine and it should not be falling apart already.
