Anyone have details? Internet says it's a very custom Android. https://www.ereaders.org/supernote-manta-versatile-durable-e...
The standard OS is derived from Android, but has no Google Play services and only supports side loading (which works well via ADB; I've not tried other app stores like FDroid). It doesn't have a lot of standard Android things like a home screen/launcher, no notifications, and no UI for switching between apps other than using the sidebar to bring up the application list and going back that way. There are no speed modes for adjusting refresh rates.
IMO, it's a great eink notepad & sketch book, and makes a good ereader with something like koreader, but it's not good as an Android tablet.
It will run most Android apps (modulo Eink screen support). The built-in note taking app is terrific.
My reasons: much better software for sketching, not bound to a single ereader app, multiple ways to send stuff around, perfect size.
Many years later, I would still choose the same. I use it to annotate webpages, sketch, read books and read queued articles in instapaper. It's distraction-free but still connected. I can Airdrop drawings or load my handwritten notes on the Macbook app. Tap to define is so good I've absent-mindedly tried it on a paper book.
The LED screen is great for some things and bad for others. You have to turn it on and unlock it. You can't SSH into it or sync your drawings as simple files. Otherwise, it's really good.
However, one thing that I think makes the biggest difference is adding a screen protector. I particularly like the ones from https://paperlike.com/. It adds a layer that makes it less like writing on glass and more like writing on paper. For me, this was the biggest increase in usability for taking notes.
