I want to express my deepest condolences at the passing of Steve Jobs, one of the founders of our industry and a true visionary. My heart goes out to his family, everyone at Apple and everyone who has been touched by his work.

Great companies have high cultures of accountability, it comes with this culture of criticism I was talking about before, and I think our culture is strong on that.

The world is changing, but so is Microsoft.

In terms of the public positioning of the company, Satya's [Nadella] done a very good job. He sort of pivoted in a way that I don't think would have been possible for me to do even if I'd seen it that way, to really talk about this mobile-first, cloud-first world.

We can believe that we know where the world should go. But unless we're in touch with our customers, our model of the world can diverge from reality. There's no substitute for innovation, of course, but innovation is no substitute for being in touch, either.

I don't think there is one size that fits all. I've been to too many meetings with journalists who spent the first 10 minutes of the meeting setting up iPad to look like a laptop.
