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

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.

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

Many companies aspire to change the world. But very few have all the elements required: talent, resources and perseverance. Microsoft has proven that it has all three in abundance.

Technologies will come and go, so you need to be able to both ask and answer the question: What do you do as a company, why do you exist?
