Our industry does not respect tradition - it only respects innovation.

Our first-party devices will light up digital work and life. Surface Pro 3 is a great example -- it is the world's best productivity tablet. In addition, we will build first-party hardware to stimulate more demand for the entire Windows ecosystem. That means at times we'll develop new categories like we did with Surface. It also means we will responsibly make the market for Windows Phone, which is our goal with the Nokia devices and services acquisition.

This notion of universal Windows apps is a very powerful concept because we're now aggregating the 300-plus-million-socket run rate of Windows into one opportunity for our developers.

A lot of people are joking about the Windows 10 error message that says 'Something Happened'. Well, that's not on me. My original idea was to not have any errors at all, and for the operating system to be called Windows RT ME One.

Microsoft is the productivity and platform company for the mobile-first and cloud-first world.

Like anyone else, a lot of what I do and how I think has been shaped by my family and my overall life experience. Many who know me say I am also defined by my curiosity and thirst for learning. I buy more books than I can finish. I sign up for more online courses than I can complete. I fundamentally believe that if you are not learning new things, you stop doing great and useful things. So family, curiosity and hunger for knowledge all define me.
