"At Apple, 99 percent of everything that was started would ship. Now, with the iPhone it took two and a half versions to finally ship it, but you knew it was going to ship. That's a very different thing in your culture. If people know it's going to ship, they invest in it. If you have a culture where you kill stuff all the time, you won't get the best out of your people, and the best people are going to walk."
-- Tony Fadell

That's not what I expected. I assumed they intentionally didn't release tons of stuff over there.
