The author suggests that Google has a unified product vision; I'd love to hear what it is. To me, Google has been all over the place in the last 5 years.
I believe it's about information flowing free and avaliable for everyone, apps running in browsers instead of the desktops and to use applications-as-a-service.
It's about data. Getting as much data as possible and putting Google in the position to launch crazily innovative products: e.g. Google Glass, automated cars.
No other company is in the position right now to develop products like that because nobody else has the data that Google has.
