Cool, that's pretty interesting. I never bothered learning the writing language for my PDA, just type my info in, so this should make it even easier to use.
Hmm... Interesting. I saw a PDA case that included a paper note pad with touch sensitive underlayment, so anything you wrote on the note pad was transferred to the corresponding PDA program, but a pen that just "beamed" the data, as it were, would be handy. (Just looked at the article... it would be niftier if the pen could actually write also. Maybe a multi-tip twisty pen style?)
Personally, I found Grafitti very easy to learn, but I tend to write in pseudo-cursive allcaps with ink pens anyhow, so it wasn't much of a change for me... The funny part is when I do a big bit of data entry on the Palm, and then go to write on paper, and find myself writing in Grafitti.
A BS, it didn't work that well, i was there watch this one instead.
(i have one :)
