My first computers were a Timex Sinclair and an Apple II.

Though many people mistakenly credit IBM with the first PC in 1981, the Apple II came out four years earlier, in 1977.

Apple's advantage is that it designs and builds software together, so if the software isn't excellent, it does the superlative hardware a disservice.

There's no other major item most of us own that is as confusing, unpredictable and unreliable as our personal computers.

I actually looked at an Apple ad from 1978. It was a print ad. That shows you how ancient it was. And it said, 'Thousands of people have discovered the Apple computer.' Thousands of people.

Arguably Apple's least successful core hardware product in decades, the Apple Watch could have been nursed along, like a terminal patient.
