"iPad backlight bleed"
You'll see that nearly ALL tablets have some backlight bleed. Mostly you will only see it in a dark room, when the screen is black
In normal use, its unnoticeable.
However, on my ASUS Transformer, I had one tiny bleed spot. I exchanged it for a unit with a much worse bleed, but paradoxically, less noticable, because it wasn't localised to a specific area.
Really, guys. If you don't see a problem in normal use, or you only see the problem when you squeeze the screen, it's not a problem at all.
