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 digital memos. These unique devices with Japanese user interfaces have become popular in and outside of Japan. They do not compete with tablet computers or ebook readers. All models up to WG-S50 have monochrome and low contrast displays, the WG-PN1 introduces an E-Ink screen. There are no apps, timers, reminders, calculators or handwriting recognition. There is no wifi or any other kind of network connectivity. Instead, the sole purpose of Sharp's WG-series is to replace paper notes and agendas with a digital handwriting solution.
