I have a Boox Note Air and completely love it. I’m waiting for a fairly large leap in display tech before upgrading (full color, more instantly responsive, greatly reduced ghosting), but if Remarkable really does require using their “cloud service” for my files, then I’ll likely stick with Boox for that reason alone. I can easily wait to upgrade until my dream display (or a close approximation of it) is developed.
Interestingly, the video about the Remarkable Paper Pro says it does not suffer from the same low-contrast/low-resolution issues of other color e-ink screens, because the display technology stack is quite different. Hope to see these devices in a store some day soon so I can lay hands on them in person.
