What ever happened to Apple 'Newton'? He-he.
Actually, Newton Handwriting Recoginition (i.e. "Rosetta") lives on in Mac OS 10.3. Hook up a graphics tablet, and then active "Inkwell" in the control panel, and start writing away. That's all it takes.
Actually, I'm writing this reply to you right NOW on my tablet. Admittedy, it is much slower than typing...
