How are your screens?
I didn't notice it until today when I was browsing webpages with white background and noticed a yellow tint at the bottom edge of the screen, where the black border and n button is located. I'm no screen expert and I don't really know what caused the issue. I know that this area is where the nook gets hot when I have wifi turned on and if this is what's causing the yellow tint then I'm screwed because... I use wifi on this a lot.
