@ton was just chatting about this with friends around the topic of the Remarkable tablet. While not for me as it is, what it helped expose is how linear platforms and formats make reading. Personally, for the non-Kindle bits, Muse has become a fav. Between the annotations and excerpts, it’s lovely. Liquid Text also helped to break up document formats to something a bit less linear. As a whole though, reading non-linear, as natural as it is, is opposite of the platforms and formats of our age... for now.
