But will all of Bezos’s risk-taking ultimately pay off? 
   "They make no money!" former Microsoft CEO Steve Ballmer 
   exclaimed in a recent TV interview. "In my world, 
   [that’s] not a real business. I get it if you don’t make 
   money for two or three years, but Amazon is, what, 21 
   years old?"

I don't know many people who have made money betting against Jeff Bezos, or lost it betting against Steve Ballmer. (iPhone, anyone?)
