Amazon Prime has 'tens of millions' of happy customers

Today at Amazon's event unveiling their Fire Phone, CEO Jeff Bezos talked about some numbers that are very important to Amazon. Specifically, he talked about Amazon's millions of Prime customers, as well as their millions of Kindle users.

As usual, Bezos didn't mention any specific numbers. There are currently tens of millions of Prime customers, as well as tens of millions of Kindle owners. These customers are apparently happy, with Amazon claiming the top spot on YouGov's customer satisfaction index. While those numbers rose steadily since the service debuted, they shot up in 2011, after the debut of the first Kindle Fire tablet. Bezos also talked about Amazon patience, persistence, and attention to detail, saying that they've been working on hardware for ten years, having worked on the original Kindle for three years before the device's launch.
