The coating on a MacBook Pro is similar to the anti-reflection coating you can get on glasses. Chlorine and heat will affect glasses, I bet the same can be said for these laptop screens. I have a feeling that with a database of 258 people, you should be able to find out what people are using to clean their screens and damaging them. Cleaning your screen using those bleach wipes is a sure fire way to damage it!
I've never used anything but water and a paper towel to clean my screen, and frankly I resent the fact that you and people like you keep assuming that it's user error. The coating is clearly defective. There is very clearly a problem with the screen coating on a (in my case) $3500 machine, and Apple needs to be called out on this one. Bravo to the OP for bring this to light.
The problem is that 258 some-odd people, out of the what, several tens of thousands of people who have experienced this issue is not a "clearly" situation.
That's, conservatively, about .1% of owners experiencing a problem, and it is entirely within reason to believe the issue is user-caused, baring some reproducible test case.
