I can definitely recommend e-readers for regular books (it's great when travelling) but for reference / textbooks I'm not sure I could. I have a Kindle Paperwhite from (I think) 2014 and it still holds up quite well. I recently read the Kleppmann book (Designing Data-Intensive Applications) on it and it was fine, but I would have liked the ability to scribble notes and put in physical bookmarks. From a technical perspective, everything worked quite well but I'm not sure I would want to read the UEFI spec on it.
