What began as a few isolated reports of mysterious stains appearing on the wrist rests of Apple Computer’s MacBooks looks to be more widespread and the impetus for a growing Web community of displeased owners. Reports of the discoloration, which seems to take place on the most frequently touched plastic areas of the white MacBooks, first surfaced in early June. A related post on an Apple discussion board got hundreds of replies–including many from MacBook owners experiencing the same problem–before it was locked by the company five days later. Apple spokeswoman Teresa Weaver said the company is aware of the customer complaints and is looking into them. She added that those customers with “technical issues” should contact AppleCare.
