The problem with the Book platform is that the media are so bulky, so while it's practical to carry one around with you and read on the bus, it's not often practical to carry two - so you're buggered if you reach the end of the story, as you then have nothing else to read.
And in these days of device convergence, Book just isn't going to catch up. The only other thing you can do with Book apart from read is scribble notes on it.
