Onyx says it is the only company that makes E Ink devices with screen sizes ranging from six inches to 13 inches. I was recently sent its latest offerings, the 13.3-inch Boox Max Lumi2 and the smaller 10.3-inch Boox Note Air2. There are some shared characteristics, including the ability to function both as an e-reader and as a content creation device. Also, both devices deploy the same Android 11 operating system and user interface, and both use the same stylus.   

Using E Ink devices for content creation is not as rare as it once was. E-reader specialist Kobo launched its Elipsa earlier this year, for example, while reMarkable is on the second version of its tablet, the reMarkable 2. 

Onyx devices are available direct online, where the Onyx Boox Max Lumi2 costs$879.99 and Boox Note Air2 costs$499.99. Both come with a sleeve and set of five stylus tips. In the UK, I found the devices without the bundled accessories at Amazon for
