I picked up another Paperwhite at Best Buy last night. I truly do not want to be Debbie Downer on here, but I'm just telling it as I see it. Three pinholes and color hues. Worst one I have seen of the 3 I've had. They had two PW display models (one wi-fi and 1 3G) and I saw faint hues on both of those as well. Mind you, the color hues were much more faint than on last years PW1 and in general the screen is much more uniform.
From what I have seen this year though the pinholes are much more prominent and the background tint still varies widely as does the brightness of the lights. The one I picked up yesterday is more blue, not as yellow. This does make the contrast appear better, but there are other issues like the pinholes. My friend has 2 pinholes on hers, but is keeping it.
Obviously I'm returning the one I picked up. I have to say from the PW2's I have seen, the PW1 had better contrast and blacker text. At least the PW1's I've seen. Just my personal experience, so please there's no need to tell me that hasn't been your experience and I'm incorrect. Everyone's experience is different, but equally valid, so hopefully this post won't open that line of discussion again.
Anyway, I'm happy for those of you that have good ones and are pleased and I'm also happy Amazon has improved the color hue issue even if it's still not where it should be, to my eyes at least. Unfortunately, overall, I remain very disappointed in Amazon's quality control on the Paperwhite.

Ah well. Maybe next year.
