Nadella: First of all, I don't think of Windows for mobile differently than Windows for HoloLens, or Windows for Xbox now. We have only one Windows. We don't have multiple Windows. They run across multiple form factors, but it's one developer platform, one store, one tool chain for developers. And you adapt it for different screen sizes and different input and output.
But what we get....I'm not trying to be another phone guy with the other person's rules. What is unique about our phones is this Continuum feature. [Continuum lets you take the screen of your Windows phone and connect it to a monitor, keyboard, and mouse, and use it like a computer].
If anything we will want to continue to build that capability out.
Just like how with Surface we were able to create a category. Three years ago most people would have said "what is a two-in-one"? And now even Apple has a two-in-one. And so three years from now, I hope that people will look and say, "oh wow, that's right, this is a phone that can also be a PC."
