From David Pogue's New York Times column. I tried Jott and I think it's great. When you are out without a pen and pencil you make a call and dictate a note etc. Then it is sent as an e-mail to yourself.

Writing it down is the only solution — so most of the time, you don’t, because you’re driving, or you have no pen, or you’re away from your computer.
