I just starting to read the new issue of Fast Company : The Great Tech War of 2012. Who will win the battle for the future of innovation economy? wooohooooooo... it really great to read it. They compare 4 companies with different starting point which has grown ahead of others to be the leader of digital world, Apple, Amazon, Google and Facebook. This is quite a thorough article on each company's excellence, competitiveness and value. And a nice reading for all the tech enthusiast out there... I will update my comment when I finish reading it.
