From a client perspective, I really think the work Microsoft's doing with Surface, with HoloLens, with Xbox, that stuff's absolutely essential to the company's future. Because innovation in the future will either be from the cloud out to all devices, or from devices as supported by software in the cloud. I think it's important for Microsoft to participate both ways.

It's how tenacious you are that will determine your success.

Our mail product, Hotmail, is the market leader globally.

I think there are lots of opportunities to improve the product. When you read the press, people say, "Oh, the product needs improvement." I look at that and say, "Hey, that's an exciting thing to get behind!" Because they can improve that product. That leaves more upside from an innovation and revenue potential than you're gonna find in a lot of places. So you could say that's a downside, I see that as an opportunity.

I think it would be absolutely reckless and irresponsible for anyone to try and break up Microsoft.

The lifeblood of our business is that R&D spend. There's nothing that flows through a pipe or down a wire or anything else. We have to continuously create new innovation that lets people do something they didn't think they could do the day before.

The way I do things I usually always prefer to have a very clear strategy and be very focused. At the same time to be very rock solid, and crisp in execution.
