Digital pens

The most unobtrusive way to digitize your notes is with a digital pen -- a special ink pen packed with electronics that can remember what you write.

Digital pens aren't perfect. They tend to be thicker, and therefore harder to write with, than ordinary ballpoint pens. They have batteries that must be charged. If you can tolerate those shortcomings, they're the closest thing available to no-compromises writing with pen-on-paper, with the additional benefit of having your scribbles captured.

Digital pens either have a wireless, Bluetooth connection to your cell phone or come with a special USB cradle for recharging and data transfer through your PC -- or both. Once the scribbles are transferred, handwriting recognition software transforms them into machine-readable text.
