I'm currently evaluating tablets and convertible laptops with digitizer screens for pen input for my office. So far I've tried the built-in pen input with Win7 Pro as well as riteScript. Both are good, but I seem to think the Win7 app is more powerful with a learning mode and available libraries (technical, medical, etc.).
Does anyone else have any experience with this technology, and if so, what handwriting software are you using?
