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.

"There's no CEO for the government." But if you were CEO for a day at the government, would you have tools and reports and wherewithal to look at government the way a business would look at its lines of business, its spending, its revenue? I've actually been working, first by myself and then with a group of people, on then on and off, and now much more on, almost since the I time left Microsoft.

I'm very, very bullish about our prospects, and as I tell our board, as I tell our employees, this is the time to invest. There's so much opportunity. Let's just invest in that opportunity, and really get after it.

I meet with Satya [Nadella] what probably amounts to four or five times a year - either to brainstorm something or just as a shareholder, we'll sit down and chat. That's always quite helpful for me and hopefully him in terms of thinking things through. I still have a number of friends and colleagues who occasionally want to brainstorm or chat about something, and that's always fun.

I'm going to f---ing bury that guy, I have done it before, and I will do it again. I'm going to f---ing kill Google.

So, I think the output of our innovation is great. We have a culture of self-improvement. I know we can continue to improve. There is no issue. But at the same time, our absolute level of output is fantastic.
