except that one month in I've started to notice slight "misting" patches where I touch the screen most - middle two-thirds up (where Google Search box comes up) and an area on the RHS from the bottom to the top where I swipe up with my thumb to close down apps etc. My guess is that it's some kind of coating that's wearing off. It's not serious and it can be buffed out but it re-appears quickly.
I am starting to get this now also right where I usually scroll up and down.
Has anyone had Apple do a replacement install with the lifetime warranty? At some point I'm going to as mine is really scratched up.
