Handwriting today: Sharp's electronic notebooks (電子ノート)

This page gives a comparative overview of Sharp's WG-series electronic notebooks for freeform handwritten memos. These unique devices with a Japanese-only user interface have become popular in and outside of Japan. They do not compete with tablet computers, their displays are monochrome and low contrast. There are no apps, timers or reminders. There is no calculator, no handwriting recognition and no network connectivity at all. Instead, the sole purpose of Sharp's WG-series is to replace paper notes and agendas with a digital handwriting solution.
