Yeah, even simple things like "See Figure 4" can become a big hassle in ebooks. (Is that on the next page? The page after?) And what you really want to do is re-read the text and then quickly look back at the figure -- which is just always going to be much easier when you're flipping back and forth between two pages that you're holding with your fingers. Maps is the other big thing. Reading a book about the Lewis and Clark expedition (or the Astoria fur-trading party), there's always one big map showing the entire route of the expedition, and you'll want to refer back to it several chapters later. Yes, you can still try to bookmark it in an ebook -- but accessing it is something like "Menu / My Bookmarks and Notes / Page forward, page forward, page forward, page forward...."
