And no one can say/predict/accurately forecast how long the coating will last. No one is saying that one month of usage is acceptable.

With over 1 million phones in circulation, it's not a problem yet and might NEVER be. I keep using the word - but it doesn't seem to be sinking in with the chicken littles - PERSPECTIVE!
Out of the millions of iPhones how do you know that there aren't many returns for the coating rubbing off? If I remember correcty, cracks didn't happen over night on the iPhone 3G but cracks were a big issue. The screen on the 3GS could be like that.
Let's give it some time.
