I thought I replied to this earlier today, but I guess I didn't hit "post"...
Either way... I can't give any real advice, because I haven't played with the Glow enough to know. I do love the regular Nook STR though, and I think it works well with light. But I would like to try the Glow, if only price would come down a bit. I'm hoping BN will have some good offers for Black Friday.
