Having made up my mind, I went to see Steve [Jobs]. I brought a hand-drawn sketch with me, and I said, "Please make something like this." He said, "Don't show me such an ugly design sketch." But he also said, "You've got the right idea. I totally agree that the time has come when we can make the ultimate mobile machine."

Whatever the country, whatever the culture, whatever the time, when you become a big enough organization, you start to collapse and slow down.

I think I would have kept in contact with venture capital investors and entrepreneurs. I'm sure staying involved as something like a coach would be fun. If I handed over the reins to a successor, I wouldn't stick around [to pull strings] like a retired emperor.

But a big paradigm shift is staring us in the face. If I left things to someone else despite having my own thoughts on it, I wouldn't be true to myself.

[Simon Segars ] came by a few times.I told him, "If you understand the future of the internet of things that much, then you should add more engineers and go on the offensive." Simon had explained to analysts and others that he intended to do that sort of forward-looking investment, but he said it's tough for a listed company considering its share price falls if profits drop.

I thought I might spend the rest of my time on golf. But thinking about it now, I'm happy playing whenever I have some downtime in my busy schedule, and even if I had all the time I wanted to play, my score probably wouldn't be very good.

I'd met Simon [Segars] for the first time in London. He struck me as a quiet, natural-born engineer and an orthodox successor [to East]. He has a home in Silicon Valley, and he said it's just a few minutes' drive away from mine.
