I currently have the high res screen on my Macbook Pro. I'm kind of wishing that I got the antiglare screen (unfortunately its past the 14 day period I can return it in). Is there anyway I can go to the Apple Store and upgrade the screen by paying the difference? I have Apple Care, so I'm not sure if that would make them more willing. What happens if some issue occurs with my laptops screen that would require a new LCD assembly to be put in? I could a request the antiglare screen then (and pay the difference obviously). I mean the normal cost of the screen would be covered by Apple Care anyway.
