Computer science is the operating system for all innovation.

I come back to the same thing: We've got the greatest pipeline in the company's history in the next 12 months, and we've had the most amazing financial results possible over the last five years, and we're predicting being back at double-digit revenue growth in fiscal year '06.

Our industry is going through quite a wave of innovation and it's being powered by a phenomenon which is referred to as the cloud.

Everyone likes to differentiate between business and consumers but I don't see the difference really. Most people are people. I get personal and business mail and I have one set of contacts from my life. I don't want to manage two sets. I want one view of my world.

When you're running a company, you have employees - lots of them - that can interrupt your schedule. You have customers that can interrupt your schedule. You have a certain obligation to wave the flag because people expect to get out and wave the flag. The number of ways that others can command your time is high. At this stage, I get to pick and choose a little more. Not that there aren't some things that have to be done, but I get a little more control over my time.

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.

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.
