Many iOS styluses have all the precision of a blunt instrument -- their thick tips frequently rule them out for handwriting. Evernote and Adonit want to refine the experience with their new Jot Script Evernote Edition. The Bluetooth-based pen has a tiny, 1.9mm (0.07in) tip that lets note takers write almost as well as they would on paper. It's meant to work with an optimized version of Evernote's Penultimate that includes zoom and improved palm rejection, but third-party software can incorporate "enhanced" control through the Jot Script developer kit. Other apps get at least basic support, Evernote says. Mobile auteurs can buy the stylus today for $75, and the corresponding Penultimate app is available for free.
