I have had my macbook for about 9 months now and have been experiencing a few problems with it. One problem is the discoloration on the back of the monitor near the heat vents. It looks like the heat has affected the color and now it constantly looks like there is dirt on it. The other problem that I have been experiencing is that the edges of my macbook on the right and left of the keyboard are starting to splinter off. I thought I only had a one time occurence when a piece of the white plastic came off on the left but just tonight on the right side of the keyboard another piece of the plastic splintered. Are these defects covered by applecare? It seems as though everything internally is good to go but I need a new case for my macbook.
