I'm putting very light pressure on my iPod screen, and a distortion appears in the left side of the iPod. It appears in the same area no matter where on the screen I tap. I'm not sure if I should ask for a replacement or not. If this is a common problem, then I'll just live with it. If not, I suppose I'll have to get a new one. Note: I'm not jamming my finger onto the screen. I'm just doing a simple tap. I need to touch it as lightly as a feather (just barely touch the screen) for the distortion to not appear.
