Totally agree with that. I normally pretty sceptical of successful people, so much of it comes down to luck, but he has left his mark on three totally separate industries, personal computing, film animation and music. It's staggering to think that one person has had such a massive influence on so many peoples lives.
* Footnote, the iPhone could be a third, but I view it as a mini computer, more than a phone, so it's almost the next evolution of the personal computer. But I wouldn't be upset if people wanted to say four industries.
