Hi, only got it yesterday. Noticed when I was walking back to it, that on an angle there is a dark patch on the screen! To be honest, it is only visible when look at an angle and on a plain white background...I think I am being paranoid. Anyone else care to look for me on theirs? Low backlight required and just a white background. I'm not going to return it, because you really cant see it unless at an angle and in law light.
