O King Portable Book Scanner

The O King book scanner takes portability to a new high. It comes with an optional plastic back plate, but the scanner can be used without it. The scanner itself folds in half, and is basically a 2MP webcam. There’s a USB port on its base where you’ll need to connect it to a computer.  The scanner costs $120.

Do you know what it would be good for? It’s small enough when collapsed that you can carry it in your luggage without serious penalty.
