I've loved my Boox Nova C color for a few years... but the ability to run Android apps including paint and drawing apps is the real showstopper. I'd love to try this tech for the paper feel but I really like the Boox interface, including their homegrown reader and notes apps. I've been really pleasantly surprised at how their software just keeps getting better and addressing minor UI issues with each (optional) update, without ever getting bloated or annoying. If anything, they've just gotten better at making their own UI more transparent and seamless. Totally apart from the great experience I've had with their hardware, I think their software is just extremely well thought out compared to almost anything else out there.
