There's no other company that could make a MacBook Air and the reason is that not only do we control the hardware, but we control the operating system. And it is the intimate interaction between the operating system and the hardware that allows us to do that. There is no intimate interaction between Windows and a Dell notebook.

It was one of those sort of apocalyptic moments. I remember within ten minutes of seeing the graphical user interface stuff, just knowing that every computer would work this way someday. It was so obvious once you saw it. It didn't require tremendous intellect. It was so clear.

It takes these very simple-minded instructions - 'Go fetch a number, add it to this number, put the result there, perceive if it's greater than this other number' - but executes them at a rate of, let's say, 1,000,000 per second. At 1,000,000 per second, the results appear to be magic.

I'm very excited about having the Internet in my den.

In order to learn how to do something well, you have to fail sometimes. In order to fail, there has to be a measurement system. And that's the problem with most philanthropy - there's no measurement system. You give somebody some money to do something and most of the time you can really never measure whether you failed or succeeded in your judgment of that person or his ideas or their implementation.

My job is not to be easy on people. My job is to take these great people we have and to push them and make them even better.
