Not the OP but I have a reMarkable tablet. I think it's far superior for writing notes (not really drawing due to the lack of color) or reading academic papers or other PDFs (that don't benefit much from color). The pen-on-paper experience is definitely better if you can look past the limitations of the display. I use it for reading and annotating academic papers or PDFs of presentations, for which I find it superior to an iPad/Apple Pencil in just about every way except for sometimes syncing and transferring documents (this would be easier on Android platforms, though perhaps not iOS). That's still a little clunky particularly if you use Linux, but there are a variety of open source tools now to facilitate the process. The tablet doesn't natively store annotations as standard PDF annotations, but it's not a proprietary format, and this only matters if you SSH in to directly access files. If you plan to get one now, consider waiting for or preordering the upcoming generation (July?).
