It's hard to invent a new thing, and it's just as hard to invent another new thing.

Getting the big things right that make all the money, that's long cycle, really executing in a way that allows you to do it, that's short cycle.

From a client perspective, I really think the work Microsoft's doing with Surface, with HoloLens, with Xbox, that stuff's absolutely essential to the company's future. Because innovation in the future will either be from the cloud out to all devices, or from devices as supported by software in the cloud. I think it's important for Microsoft to participate both ways.

The lifeblood of our business is that R&D spend. There's nothing that flows through a pipe or down a wire or anything else. We have to continuously create new innovation that lets people do something they didn't think they could do the day before.

I like to tell people that all of our products and business will go through three phases. There's vision, patience, and execution.

It's hard to invent a new thing, and it's just as hard to invent another new thing.
