The BOOX Tab Ultra C Pro is probably closest to what you’re looking for. It’s basically a full fledged Android Tablet, just with an eInk screen. It even has a camera you can use for document scanning and such, and a pressure sensitive stylus powered by WACOM tech. Of course, this hinges on if you can find the apps you need on Android. I love Android, but Apple definitely has a leg up when it comes to proprietary productivity and creative apps.

I personally have a BOOX Nova Air C which is a 7.8in model from a couple years ago, which has a color eInk screen, Bluetooth, Mic, Speakers, Stylus, Android 11, and the full Google Play Store. I personally use it mostly for reading, but the stylus works really well for taking notes, and I’ve even played games on it (GameBoy Tetris for the win).
