It's been ages since I've read a non-fiction book from cover to cover. It would have been far more valuable to read Negroponte's work back when it was originally published, because he was predicting the future. He foresaw Netflix, the rise of massively-multiplayer online video games like World of Warcraft, smart homes, and much more. A few of his ideas have yet to come to pass, and until Roombas learn to recognize the difference between animal dung and dust it may be a while yet to come.
If you're at all interested in the actual meaning of "digital", the first chapter of this book is an excellent primer. Now I'm off to find some books a little closer to the bleeding edge of things.
