Seems like total BS to me.
The color nooks is:
210 x 130 x 12mm
Standard CD Jewel case is(smaller in every dimension):
141 x 124 x 10mm
I don't think Pocket size increases that much with waist size.
I wear size 32". I don't have a Color nook , but I do have standard CD case jewel case (thicker old style).
I tried every pair of jeans I own and CD Jewel case is not even close to fitting in back pocket of any of them, including two different pairs of Levis.
For wide load types it may fit partially into a back pocket of some jean, but it would seem to be fairly idiotic to carry it that way even if you could jam half of it into a back pocket.
Since I have both the jeans and the Nook Color, I can confirm exactly what I claimed.
EDIT: And just for giggles I confirmed again in a pair of 505 straight-fits. It fits width wise just fine, tho the pocket isn't nearly deep enough for me to trust walking around with it for long.
EDIT2: the original Levi Slim-fits I mentioned were a 36, and not a 34 waist. My bad. The 505 Straights are a 34
