I've been taking pictures of business cards and sending them to Evernote. This works really well because the system does optical character recognition on the text on the cards, and makes it searchable. Very impressive, all the more so because it actually works.
For the best results I used a setting on the camera which is specially for taking pictures of text. Out of interest I pointed the camera at myself and took a picture. I got an image with the word "Rob" on it.
