I thought you might find this interesting. I bought my MacBook the day they came out at the San Francisco Apple store. I've had major discoloration with it (partly because my work environment is so dusty).

I was going to take it to the Apple Store (as noted they will replace or do whatever with the plastic). Then, today, I looked at the dirty edge of my MacBook, and it was -- for lack of a better word -- fraying. With a little nudging, the "surface" of my dingy MacBook began to peel away, revealing a beautiful white plastic underneath.

My MacBook had been running very hot for about 30-45 minutes before this happened (I was doing some heavy processing). Since my MacBook has cooled it has stopped peeling.

So, either someone somewhere forgot to take the protective coating off my MacBook, or I've burned through an intended layer of plastic. This is odd, as I've previously tried various ways of "cleaning" my MacBook to no avail -- strange it should just start to peel now.

I don't know if this is the reason for anyone else's discoloring, or if mine (with this layer peeling away) will start to discolor in different ways. In any case, that's my story.

Sorry the photos are so blurry, the only camera I had on hand was my Pocket PC (ick!).
