Looking forward to reading about your experiences. I bought a Boox Nova 2 last summer for the same reasons, to better read and write. While I am very pleased with the e-ink device and enjoy the reading (including magazines) and writing I do on it, I haven’t had much benefit from it yet in terms of a significantly higher volume / deeper form of reading, as my habits around it are still lacking.
Sitting at the breakfast table writing what will become a blog post on drop in audio. Yes, it’s a new reMarkable “paper” tablet. I’m using it in the hopes of better deep reading and writing. Except for a quick microblog to post a picture of it!
