I started another thread on this where after receiving my replacement nexus 10 I gave it a thorough inspection and I did not find any dust. After leaving it in a bag for a couple of days I find a small, almost invisible hair that I am 99% certain was not there when I received it. Normally I would accept that I may have just missed it, but it I looked this thing over for quite a long while before I gave it the ok. I'm debating whether or not to send it into samsung because I fear this same thing could happen again, or I could receive a unit with horrendous light bleed or more dust, as both seem pretty common. However I thought I read somewhere that these screens were sealed and the glass could not be separated from the display? Perhaps the glass and the display are fused to the frame, but not to each other or the seal is not the best.

Shine a really bright light on the screen and turn your device on an extreme angle so that you're almost looking at its side, but you can still see the screen. Is it me or can you see Foam bonding it? I don't think you would be able to make that out if the glass rested directly on the display. You can see it in the picture below. It's the light gray line.
