The Remarkable and Onyx Boox Max Carta are two devices that are geared towards digital note taking. The Onyx is more of a multimedia device; it runs Android and has Google Play to install apps, but screen can only be interacted with via the stylus and it does not have pressure sensitivity. The Remarkable stylus has over 2,000 degrees of pressure sensitivity and has a better functionality for drawing or taking notes than the Onyx.
In this comparison video we go over all of the core functionality of both of these devices to give you a sense on what they both bring to the table. We devote a lot of time to the drawing and note taking experience and go over everything that you can do.
