I think this bit really sums up the whole thing nicely:
The only thing we’ll never do is make a crappy product. We’re going to make a great product. That’s the only religion that we have. We must do something great, something bold, something ambitious. We want the customer to be the center of it. We want to enrich people’s lives. And all of this other stuff, we sweat the details on those, in hopes that we’ve proven over the years that this is something we can do.
