Be passionate and bold. Always keep learning. You stop doing useful things if you don't learn.

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.
