I read books on an eBook reader most of the time but one thing that's really lacking is ease of skipping around to different sections, reference pages etc. Having said that, there's a lot of obvious effort in the software to help get around that limitation (footnotes appearing in a popup window, searching the book for any text, bookmarks, etc).
