Boox is not the best company as far as longevity of products (software updates) and their disregard for following open source licensing, as others have mentioned here.

That said, I recently bought this exact tablet. The software on it is functionally great, and the colors, while muted, seem great for comics, and art/drawings, but not photos. Videos are completely out, though it’s neat to kind of see how it would work on e ink. For me, I’m using it to read longer posts from my rss feed and for books. I’m also planning to try testing using it as a second display for my laptop, so I have something to look at with less eye strain. Eye strain from my phone/laptop was a big pull for me getting an e ink device with android vs something like the remarkable or even a kindle. Maybe I’ll get into manga or comics too. Unless you have a need for color, if you already have a good e ink device, I’m not sure I’d recommend it. Really hope a solid competitor arrives in this space soon, though, or alternatively if Boox would just open source their software.
