Most inventors and engineers I've met are like me. They're shy and they live in their heads. The very best of them are artists. And artists work best alone.

My whole life had been designing computers I could never build.

When you're designing and inventing the way I did, every minute of your life is put - every neuron in your brain into trying to think about the little code and how you can maybe have one less line of code and a little bit more straightforward from the beginning to the answer. And you don't have time to think about companies and products and how would I build this. So Steve Jobs and I were a very necessary pair.

I never sensed really bad blood between Microsoft and Apple. A lot of Macintosh users feel badly about PCs and do have some bad feelings. I call them Macintosh bigots a little. They say, oh, no, only the Macintosh is the good one, and I don't like to be that way.

In the end, I hope there's a little note somewhere that says I designed a good computer.

Steve Jobs had very strong feelings about what makes a company great, what makes products great. He more or less chose Tim Cook to be in that role, in that position.

Everything that has a computer in will fail. Everything in your life, from a watch to a car to a radio, to an iPhone, it will fail if it have a computer in it.
