Footnotes at the end of the book used to bother me because it screwed up my "furthest read page" when I wanted to open it in another device - but now I can reset the furthest read page from Manage Your Kindle so it doesn't bother me as much. Still, I prefer when they are listed at the end of the chapter instead of the end of the book.
Otherwise, it's really only charts and maps that wind up being too small to read which bother me. Pictures aren't ideal on Kindle if they're in color but it doesn't bother me too much.
