Okay so I’ve been using the Sony Readers since PRS-500 which predates the touch interface. I’ve never been happy with how they handled footnotes. You would be taken out of the text to jump to the footnote probably at the end of the chapter and then you’d have to hit the back button to jump back… Of course if for some reason the footnote paginated … anyways.
My experience with the Kobo Aura and footnotes has been much better. A small dialogue box pops up with the text of the footnote over the text which I can easily dismiss. I don’t feel like I’m bouncing back and forth in the book. I suppose I should include pictures and what not but I’m not going to because I doubt anyone really cares about this sort of thing. I mean anyone else.
