If you don't have a real stake in the new, then just surviving on the old - even if it is about efficiency - I don't think is a long-term game.

To me, what Minecraft represents is more than a hit game franchise. It's this open-world platform. If you think about it, it's the one game parents want their kids to play.

You've got to remember even the Apple regeneration started with colorful iMacs. So let us first get the colorful iMacs. I think with what we're doing with Lumia, we're at that stage. I want to do good devices that people like, and then we will go on to doing the next thing and the next thing.

When we think about Windows, we want to think of it as a broad platform, from wearables to industrial IoT platforms to PCs and tablets.

I think reconceptualizing Microsoft as a devices and services company is absolutely what our vision is all about. Office 365 and Azure on the services side are representative of it.

One of the things I think a lot about, I am perhaps a great example of the enlightened immigration policy of this country where I was able to come here to study and then stay back and work and build a life.
