The PalmPilot and its descendants have been around for almost a decade, but some people still aren’t convinced that they need one. Now there’s a Palm that will overcome their objections. The PaperPalm costs only five dollars, doesn’t require batteries, and can be dropped on a hard floor without breaking. There’s no software to install, and no learning curve. You don’t even need to use Graffiti — it can process your natural handwriting without error. But you may have to sharpen the stylus first.
