The linked demo is by far the most impressive thing I've seen all week. I wish a certain Microsoft chart editor was as easy and unfinicky to use as this demo from 1966 (52 years ago), and that's still one of the better editors out there.

Comparing this with the Graffiti system on my old (2000-ish) Palm Pilot, this is somewhat more reliable even on a first attempt than that was after I'd made a concerted effort to learn it. Very cool!

Edit: I think where the Afterword says "inputting text with a stylus is likely slower than touch typing", they're forgetting that we still don't have a really acceptable way of inputting text on mobile devices. Swype and its ilk are close, but still hamfisted at times.
