Yes!

I'm on this route myself, trying various things out at https://github.com/fenollp/reMarkable-tools

Handwriting (in and out) support is very important IMO. Also being able to draw DAGs.

I'd like an e-ink device with high frame rate and HW powerful enough to run some models locally or with good enough connectivity and sensors that e.g. Computer Vision tasks can be offloaded to the users' smartphone.

Feel free to expose your ideas on there :) I welcome Open Source discussion!
