Bezos thinks $30 is too expensive for a book, since most books are competing for your attention with content that's free or less expensive.
This could include anything from a blog to a video game to a mobile app, according to Bezos.
The bottom line, he says, is that books aren't only competing against other books anymore, so the pricing should reflect that.
"If you realize that you're really competing against 'Candy Crush,' you'd say, 'Gosh, maybe we should think about reducing friction on long form reading. That's what Kindle has been about from the very beginning."
