Interesting read. To go from concept to product is pretty amazing.
They mention that people buy into an ecosystem. It's interesting that within the last 4 months the Android Market became Google Play, more of an ecosystem. So at the same time Asus was working on this tablet, Google was in the process of redesigning their ecosystem.
I still prefer the Android Market. I also can't see myself ever buying a book, downloading music or renting a movie from Google. Amazon is cheaper and Netflix is way more cost effective.
