My 2015 13" MBP has a few tiny little specks on the screen, and the won't rub off with a microfiber. I'm pretty sure they are tiny, tiny scratches. I had the same thing on my old MBA, but only after I used it for 2 or 3 years. This MBP is like a month old and it already has these things. Am I doing something wrong? Or is this considered typical "wear and tear?"
