Google has a digital handwriting Progressive Web App it calls Cursive that can now be installed on any Chromebook. However, since you cannot type in it, it’s only useful with a stylus. The news gave me an excuse to drag out to the Lenovo USI Stylus that I have to test the app on the Lenovo Duet. Bottom line is that this combo is only really useful for quick and dirty notes or sketches, the latency between the pen and the Chromebook is so bad that writing for any length of time will drive one crazy.
