I was announcing to the public, in 2006, that I'd be leaving Microsoft in a couple of years and focusing full-time on the foundation. That was the time at which we went back to New York and Warren [Buffett] announced these gifts to a number of foundations, with a very high percentage of it going to us and basically doubling our capacity.

Money has no utility to me beyond a certain point.

I regret being the richest man in the world because that position attracts undeserved publicity.

The most important work I got a chance to be involved in, no matter what I do, is the personal computer... I even knew not to get married until later because I was so obsessed with it. That's my life's work.

Paul and I, we never thought that we would make much money out of the thing. We just loved writing software.

We [Corbis] make it so easy to call up images, whether art or people or beaches or sunsets or Nobel Prize winners.

Microsoft's philosophy is to 'do things better.' And Vista has given us lots of opportunity to do that.
