Pen-Based Computing Breakthroughs

From the New York Times: Take Note: Computing Takes Up Pen, Again

"An ambitious new type of pen-based computer system could bridge the gap between paper and the digital world."

"The Livescribe pen is a more advanced version of the LeapFrog Fly Pentop Computer, which itself has some impressive abilities, even if it is intended for children. Fly users can draw a calculator on paper and make it work by tapping the keys with the pen; a speaker in the pen plays back the results. Users can also draw a piano keyboard on a piece of paper and play a tune on it."
