Satya Nadella has been CEO of Microsoft for five months, and he's made it clear he intends to change and re-focus the software behemoth as it navigates the next generation of technological change. To mark the closing of Microsoft's fiscal year, Nadella released a long, detailed memo laying out his grand vision for the future of Microsoft. He talked about the importance of mobile and the cloud, the end of Microsoft's focus on devices and services, and laid the foundation for big changes in Redmond. "I consider the job before us to be bolder and more ambitious than anything we have ever done," he said.

We had a few questions for Nadella after we read the memo, so I gave him a call to talk about what the future of Microsoft looks like under its new CEO.
