I've noticed this with my Kobo ereader (which I love). If I want to go back a few pages, and then return to where I am now, it's a whole ordeal. The UX is there, but I have to learn it and remember it, and it's different for every device (not that I use many different devices). All physical books, miraculously, have the same UX.

The parent post to yours makes me think that a large e-ink display would be useful in a school setting. Rather than carry around a backpack of enormous overpriced textbooks that we might use 30% of in a semester, just have one large ereader that you can use from 1st grade through your PhD.

It's like a book, but lighter! And no internet, no games, no social media, no animations. No private enterprise capturing public education to sell schools a bunch of stupid shit. Just an improvement on a stack of textbooks, which schools or parents have always paid for. Might be nice.
