Very interesting blog post over at Dear Author about customising car dashboards, and smart phone displays, and, eventually, ebooks. I agree with everything Jane says. The comments are also interesting--particularly the one about customising book files for printing via Espresso POD machines. I don't know if publishers do this yet, but they should. Imagine if you could print out the book any way you like, perhaps even personalise by adding photos. (But then I imagine one would run into copyright knots.)
Does anyone out there have experience of Espresso and its custom options? I don't know enough, clearly.
