I just noticed this today: Well I just got my MacBook 3 months ago(for Christmas). It was brand new and nothing seemed to be wrong. I've never dropped it or hit it or something like that. When I turn it around and its closed, the bottom part(turned around) where the screen connects with the bottom piece is cracked on both sides. It looks weird. In the picture you can hardly see it(bad camera, sorry!) but you can see it when you are looking at it for real. Should I be concerned?
