My apologies if this has already been addressed. I got a white macbook when it first came out and of course it had the infamous "smudge problem". Within two weeks it had a weird yellowing discoloration around the mouse pad, etc. Anyways, I took it into the apple store and they replaced the bottom panel where the mouse pad was. This past week I noticed on the bottom end of this panel (down where the mouse pad is) there seems to be some separation. IE. the thin lining in between the panel and the base are starting to chip off. In fact, I'd say there are now two 1.5 inch chips. One of which fell off. Has anyone had this with macbooks they had "fixed" of the smudge problem? I am hoping I can go into the store and say because of their replacement this thing happened and that I will be covered.
