My wife's has a good amount of micro scratches. Nothing that is immediately apparent when looking at it, but they show in bright sunlight.
The glass screen protectors work great. She had one on there, cracked it, and just never replaced it. If you don't mind them not having full coverage (s
ome do but they are essentially just an aluminum border) they look fine IMO. Feel like glass (because they are glass) and they are perfectly clear.
The way I look at this, and not everyone will agree, is that this evice isn;t something I am likely to keep beyond 2-3 years. I have no real interest in limiting scratches so that the next guy who gives me pennies on the dollar gets a flawless screen.
Apple finally gave me the things I felt I needed to make a purchase worth it, but there is a lot of room for advancement here. Maybe years down the road, if I am still interested in this tech, I will drop some more money. Right now this is a completely disposable product in my eyes.
