While having an e-reader is awesome for reading before bed, sometimes you just want to curl up with an actual book. The smell, the feel, and having to turn every once in a while because the book gets to be too heavy is just not something you can recreate any other way. The only annoying part about about switching from e-reader to book is not having it backlit, which means you need a light.
Having a full-on bedside lamp may be a bit excessive, which is why a book light would be a much better option. The Tiny Book Light looks like the baby brother of Luxo Jr., and can clip onto the front or back cover of the book. This little guy is only five inches tall, and will cost you about $10. When not clipped onto a book, it can function as a little lamp for whenever you should need it.
