Take a lot of notes? Then consider investing in a Livescribe Pulse Smartpen ($100). Available with 1GB or 2GB of internal storage, the Pulse has a microphone, camera, and special paper that allows it to make a digital record of your writing and associate it with the audio it captured at the time you were writing. Watch this for an example. It also features an OLED display, and has a growing developer community working on new ways to use the device — meaning it might become even more useful after you buy it.
