I think I probably know the answer, but Barnes and Noble just came out with the Nook Glow reader where the light comes from within the device instead of having light shine from an external source. At first I thought it sounded like a perfect solution for reading in bed to get sleepy, but then I wondered about what kind of light it uses. Anyone know? Would it keep you more awake than sleepy? I think it's LED lighting but I'm not sure.
