The Livescribe 3 Smartpen is the latest electronic pen from California-based Livescribe. Designed to take the pain out of digitizing, archiving and sharing handwritten notes and sound recordings, its wide-ranging appeal spans anyone from note-taking business people to list-scribbling shoppers.As with Livescribe's previous smartens, the latest model will only digitise your written notes when used with the company's proprietary dotted paper, which is supplied in a spiral-bound notebook. That's because the pen (somewhat disappointingly) doesn't work by magic - it houses a tiny infrared camera in the tip that reads the dots to help it track its position and digitize your pen strokes.
