Kindle and iBooks seem to have the goal of reproducing what is possible in paper books. Yes, iBooks supports embedded video and audio content, but it does so in a way that feels as though Apple pondered what it would be like if you could play video on a piece of paper. Push Pop’s concept strikes me as far more ambitious: What can we do with the idea of a “book” if we eliminate the limitations of ink and paper, rather than mimic them? E-books that aren’t merely rendered by software, but rather e-books that are software.
