I think technology advanced faster than anticipated. In that whirlwind, a lot of companies didn't survive. The reason we have done well is because, even in that whirlwind, we kept heads-down focused on the customers. All the metrics that we can track about customers have improved every year.

You know, if you make a customer unhappy they won't tell five friends, they'll tell 5,000 friends. So, we are at a point now where we have all of the things we need to build an important and lasting company, and if we don't, it will be shame on us.

We want to make money when people use our devices-not when people buy our devices. We think this aligns us better with customers. For example, we don't need our customers to be on the upgrade treadmill. We can be very happy to see people still using four-year-old Kindles!

We've done price elasticity studies, and the answer is always that we should raise prices. We don't do that because we believe, and we have to take this as an article of faith, that by keeping our prices very, very low, we earn trust with customers over time, and that actually does maximize free cash flow over the long term.

If we can arrange things in such a way that our interests are aligned with our customers, then in the long term that will work out really well for customers and it will work out really well for Amazon.

I constantly remind our employees to be afraid, to wake up every morning terrified. Not of our competition, but of our customers.
