The only quibble I have is that I am reading a Jen Lancaster memoir and she uses a lot of footnotes. Occasionally it takes a couple tries of pressing in the right place/pressure to bring up the footnote instead of the next page or the dictionary. (or the menu/previous page depending on what part of the screen the footnote is on.)
Yeah. The eInk displays are awesome, but the more complicated the document in terms of formatting and footnotes and illustrations and so forth, the trickier the eInk displays are to use.
