Digitopoly: JK Rowling blows up the eBookstore business.

"You purchase once and you can get the book on any device. And I mean any. Kindle, iPad (through iBooks), Google Play (whatever that is) and Sony who appear to have provided the technical grunt to get this working. There is no other major book that is available this way. Actually, probably no other paid book available this way.

…

So what does this mean? The whole concern over eBooks was potential device lock-in. We are worried about being tied to Amazon or Apple or what have you forever. This same thing is preventing entry or inroads by others such as Sony. The Rowling initiative breaks through all of that. It is device independent for the first time in this industry."

There's obviously other books that have gone this route- but nobody this big has done it before today. The future of publishing is awesome.
