It is an interesting idea, but with a physical book you have to turn the page. And that has to be more distracting, because you can't read any part of the page while it is turning. But I also had the experience once (and I think most readers has had it more than once) of reading a book and having to stop because somebody turned the lights off - then realizing that I had been so engrossed in a book that several hours had gone by and the sun had gone down by then.
