I just got a new blackbook and I noticed if I put it in my backpack for a while there would be a line on the screen, where the top of the trackpad meets the keyboard. Now I am wondering if this may become a potential issue of the screen getting scratched up over the years, or months which would sick, and I would like to avoid this issue now I guess. I have the incase hard shell on, maybe that is causing more pressure on the screen? how should I deal with this. the line can be wiped off, maybe its just my keyboard is dirty.
