This is a 1-gig flash drive that one of my dogs mistook for a small chew toy. After I retrieved it from his mouth I looked at it a little closer. This teeny device is capable of holding 500,000 books. At a quick estimation I probably have about 1000 books in my house. The thought that they (and 500 times them) can fit in this teeny thing is both amazing and a little scary to me. And even more scary is that ten years from now (or much less) this flash drive will look like a cumbersome giant. I truly hope that books never entirely disappear.
