I meet with Satya [Nadella] what probably amounts to four or five times a year - either to brainstorm something or just as a shareholder, we'll sit down and chat. That's always quite helpful for me and hopefully him in terms of thinking things through. I still have a number of friends and colleagues who occasionally want to brainstorm or chat about something, and that's always fun.

Great companies with the way they work, first start with great leaders.

I think PCs are going to continue to shift in form factor. The real question is: What's a PC?

As a shareholder I have expressed my frustration with not getting more information about revenue and margins from the cloud.

Our goal in making these changes is to enable Microsoft to achieve greater agility in managing the incredible growth ahead and executing our software-based services strategy.

In terms of the public positioning of the company, Satya's [Nadella] done a very good job. He sort of pivoted in a way that I don't think would have been possible for me to do even if I'd seen it that way, to really talk about this mobile-first, cloud-first world.

The one thing that I think separates Microsoft from a lot of other people is we make bold bets. We're persistent about them, but we make them. A lot of people won't make a bold bet. A bold bet doesn't assure you of winning, but if you make no bold bets you can't continue to succeed. Our industry doesn't allow you to rest on your laurels forever. I mean, you can milk any great idea. Any idea that turns out to be truly great can be harvested for tens of years. On the other hand, if you want to continue to be great, you've got to bet on new things, big, bold bets.
