Some of you may have heard of this problem with aluminum PowerBooks -- corrosion or "pitting" of the aluminum surface to the left and right of the trackpad area (1, 2, 3). But you've never seen a worse case than my poor little 12" PowerBook. I mean, check that out! the epicenters of the two problem areas map to the bases of my palms at rest. Apparently my body chemistry is on the caustic side -- must be all those Sour Patch Kids. This actually doesn't bug me terribly, but I'm coming up on the end of my warranty and am not planning on buying AppleCare, so now's the time to get it fixed. Though certain individuals have gotten this taken care of, Apple has no official program yet. So if you have this problem on your PowerBook, pipe up now! Post here, and call Apple (politely, of course). Alternatively, perhaps we can open a sideline business that makes replacement palmrests from birch veneer.
