Paper UI beats digital in a lot of ways. I haven’t replaced my several-hundred book library with ebooks not because I love all these heavy, bulky objects, but because the UI of an ebook is a lot worse for anything but entirely linear cotton-candy fiction reading. It’s got (enormous) advantages on weight, searchability (… though, a good index is better IMO) and not needing separate large-print editions for some readers, but basically everything else about the UI is worse.

I’d be thrilled if ebook devices could somehow close that gap.
