@zer0hedge amazon may have its share detractors but there is no doubt about their customer orientation. There's a joke that does the round about banking service being an oxymoron and it's true to an extent - any kind of service from banks is usually terrible and customer orientation is even worse. That's one reason why people hate banks ...
Given how customer centric amazon is, if they do start financial services, I'm sure a lot of customers would buy into them.
