Does anybody else have a bluish shadow at the very top of their retina Mini (along the side with the Facetime camera)? I haven't seen an iPad Air yet in person, but I'm wondering if this is similar to what the Air owners are calling the book-spine effect. I took a picture so you can sort of see what I'm talking about. The picture isn't the best, but it shows just how much of a shadow I have on one side of the screen. In this picture, the shadow is on the left where the Facetime camera is and the Home button is on the right. I also have mild yellowing on the home button side at the bottom of the iPad, but it's not as easy to see in this pic, although you can still tell. When reading from left to right in landscape mode, the experience is: dark bluish shadow -> bright white -> dimmer and yellowing This is a Week 51 rMini, so definitely one of the later ones, which doesn't make me too optimistic about exchanging it for a new one.
