Software Garden Products: Dan Bricklin's Note Taker App:
"Dan Bricklin's Note Taker App (a Software Garden product) is an app for the Apple iPhone and iPod touch.I had fun playing with this app.
Note Taker makes it easy for you to quickly write down names, phone numbers, addresses, shopping lists, notes, and more. You write directly on the screen with your finger. No need to fumble with letter and number keyboards while someone is giving you information, or ask them to slow down while you try to edit typos. It's like having a stack of note cards and a pencil always with you."
You can get a free trial version at the iTunes store.
