Personally I find books are just as capable of engagement as TV or the internet, and I actually have an iPad in my bedroom for the same logic as jgc has a kindle. On it I have TV shows that I've seen many times (a few favourites such as The West Wing), to the point that I still enjoy watching them, but at the same time know what is about to happen. These are great for getting me to sleep, and because I'm not having to actively concentrate on what I'm reading, I can fall asleep as soon as I'm ready to, while the iPad plays on in the background - unlike a book, where I have to actively decide when to make the switch from reading to sleeping.
