Yes that´s what I believe too, but still you cannot take it off like a screen protector, which makes it part of the screen and if it gets scratches, game over.
I agree with you 100%. If it rubs off in one spot (like where you always slide to unlock) what do you do then? Just have a permanent spot on your screen? That same area is not affected on the iPhone 3G (no coating). So I think the oleophobic layer has the potential to be a bigger problem in the future when people have had their iPhone 3GS for 12 months.
I too heard that the coating is scratching easier. This means people can't treat this new iPhone the same way they treated their iPhone 3G. They can't press as hard on the screen now and they have to worry about anything hard touching the glass?
I totally see where you are coming from man... I really do. I think Apple should take the coating off of the next model. Sure it feels nice, but once it wears or scratches, you'll be wishing the coating was never there in the first place.
