Capturing writing in a pen

The New York Times [free reg req'd] has had a look at a couple of pens that capture your handwriting so you can transfer it to a PC. The Logitech Io is actually the Anoto, from Sweden, which won a Best of Comdex award in November 2000. (The Sony Ericsson Chatpen is also an Anoto.) The other product in the NYT review is the Seiko Ink Link, which came out last year. There's a more useful review here.
