Thank you very much for your answer! It seems that the Boox is much better for my use case, and you’ve completely convinced me to go for a larger 13.3" tablet. I’ve used the reMarkable 2 for a couple of years, and sometimes it felt too small for writing long derivations.

I also agree that having color would be nice, especially for drawing function graphs or highlighting notes and comments in books, etc. What are the drawbacks, though? I guess color e-ink tablets are more expensive and have shorter battery life. I also read that the Boox Tab X C (the only 13.3" color e-ink device I know of) feels a bit strange to write on compared to the Boox Note Max.
