It doesn't make any sense to me for the author to compare three companies that have nothing to do with each other. One if a all-purpose retailer, one a hardware company and one sells advertising. That being said, Amazon is the runaway freight train in online retailing. With sales of $24.5 billion, there isn't anyone else even remotely close. Staples is no.2 at $9.5 billion and Walmart is an order of magnitude smaller than Amazon. Amazon are on a tear this quarter with net sales growing 40%. Now you add in their position as a leader in cloud-computing, along with the kindle.. and I think their future prospects are great.
