The Nokia pen is similar to the Logitech. It uses real ink and requires special paper, which you must either buy from Nokia or print yourself from a special printable PDF file that comes with the pen.

The SU-1B synchs with your PC using a USB cradle and also connects via Bluetooth to a Nokia 3650, 3660, 6600, 6650 or 7650 cell phone, which enables your writing to be sent via e-mail or SMS. However, it's sent as a picture, not text.

Little lights and a vibrating feature alert you to its battery and "send" status. It also features 1 MB of memory in which you can store about 100 pages.

Digital notepads

Digital notepads work like Tablet PCs in that you use a stylus to write on a touch-sensitive screen, but they cost much less (under $200 instead of around $2,000). To transfer data to a PC, you simply connect the tablet via USB connection and synchronize with special desktop software.
