I would recommend looking at the Supernote. I did a ton of research and the ReMarkable seems very oddly limited. Supernote A5X is one of the best purchases I’ve made in 10 years easily.
Idk about hackability and whatnot but as far as a useful e-reader, note book, sketchbook, planner, it’s amazing.

Configurable, highly linked PDF planner with a very responsive person behind it (I figure he must be around here somewhere :))
