This dates back a couple of years, but I first ran across it in a Facebook re-blog yesterday.
Ironic, isn’t it? The idea of using an e-book reader as a bookmark in a paper book? But if you think about it for a bit, it makes sense. They made the book reader so thin and light that naturally if you’re looking for something to keep your place in a paper book and you can’t find anything else…well, why not?
