Overall, I agree. The thing I like most about my e-ink nook is that the only thing it can do is reading, as opposed to the iPad, which always has the temptation to play a game, or check the web, or chase that ding which means new mail.

That said, I think that HTML5 capabilities can improve the reading experience if used properly. iPad-type tablets can get access to interactive experiences with technical books and comics, kindle-type tablets get improved typography and layout. Some publishers may abuse the tech, but there's still a very strong market for Just Plain Reading, so I don't think it will be too bad.
