The problem with the Nook Glowlight is that the diffusion layer on top of the screen is extremely susceptible to damage which shows up as a bright spot whenever the light is on. Even a very minor knock against the screen is apparently sufficient (one person on the Nook forums said that it happened when she dropped a mini-USB plug on her Glowlight), and there have been a number of reports of Glowlight units fresh out of the box showing signs of damage, or hot spots spontaneously appearing after a few weeks.
So whatever technology Kobo is using on the Glo, lets hope it's at least robust enough to stand up to the rigors of normal use.
