The flashing for black text on white background never bothered me and I stopped even noticing it very quickly when I got my first e-ink reader. The flashing for white text on a black background is still quite noticeable during the day and bothers me at night.

I am impressed that they can do 20 page turns without ghosting. I remember when I could see ghosting after 2 page turns without refresh and 3 or 4 were really bad. (That was after devices had an option to go 6 pages without refresh.) Just bringing up a menu then going back to reading would leave a horrible menu ghost.

But, still, they need to do something about the white flashing in a dark room. The inverted colors are an accessibility feature, after all. The flashing may be inherent in the display, but the frontlight can be automatically turned off while it is happening.
