Hot on the heels of the news of flaking black MacBooks are reports that white MacBooks are exhibiting strange discolorations on the palmrest area. A user has even set up a website documenting the problem and claiming that 38 users have contacted them with similar complaints. It should be obvious that the problem doesn’t affect all MacBooks (my sister has a white MacBook that has no problems, for example) but it is possible that the materials used in the case somehow react with certain people’s body chemistry. There were scattered reports of the aluminum PowerBooks having problems with their palm rests actually getting tiny holes in them, apparently because of some kind of reaction with the sweat in the user’s hands. It will be interesting to see how this story plays out.
[Edit: Apple is apparently providing service for people affected by this problem.]
