Recently, Marc mentioned that the light from the iPad may be bad for me to look at before going to sleep. He'd read about such light interfering with the mind's process of getting ready to sleep. Since I do most of my reading before going to sleep, this did seem like a serious issue, especially since I don't sleep enough as it is.
So I decided to brush off the old Nook, charge it and start using it again. I'm not sure if it makes for a better sleep experience so far, although I think it may, but one thing I noticed is that it is a better reading experience. It's not just that the Nook screen is easier on the eyes (which it is), but rather that there are fewer distractions. With the iPad, I would check e-mail, respond when a Facebook notification came up, etc. With the Nook, I just concentrate on reading the book. Definitely a better way to go!
