What would the world be like, if you could instantly buy every book as an ebook anywhere in the world, if ereaders were clearly more convenient to use than paperbooks and if they were so cheap, that everybody who now owns 1 book would own 1 ereader? I might be wrong, but in my imagination this would be awesome, offering nearly limitless possibilities for disruption. For example the adoption of open-source textbooks in schools would be much easier, academic research in some countries would really benefit from easier access to materials. I think there is no question that this will be technologically feasible at some point in the future. The question is, if it happens and when. I hope it happens as fast as possible and judging by the development of the ebook world from 1990-2007 and 2007-Now, Amazon is by far more beneficial than the traditional publishers in this regard. Certainly a monopoly is never optimal, but let's worry about that once the future has arrived. There is always antitrust law. Until then, I hope Amazon (or Google or Apple or ...) achieves as much marketshare as possible and pushes the development onward.
