Our ambitions are bold and so must be our desire to change and evolve our culture.

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.

The opportunity ahead for Microsoft is vast, but to seize it, we must focus clearly, move faster and continue to transform. A big part of my job is to accelerate our ability to bring innovative products to our customers more quickly.

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.

The way I measure my life is 'Am I better than I was last year?'

Our mission of empowering every person and every organization on the planet to achieve more is really a look back to the very creation of Microsoft.

What was true then and what is true now is that we create technology so others can create more technology.
