[QuantumIguana]

For me, the main advantage of the Paperwhite is that I can read in a dark room. When I'm done reading for the night, it's nice to not have to get out of bed to turn off the light. I'm perfectly capable of reading on a non-lighted Kindle.

We use the word "book" for both the content and the medium, and that leads to confusion. "Codex" is a perfectly good word for a paper book, and avoids confusion.
