One thing that's interesting: Steve dogfooding that single button mouse. Image was from 2004, but still – figured he'd be using a multi-button mouse like the rest of us were back then.
As far as I remember there was no multi-button mouse by Apple in 2004.
Most people were using third-party multibutton mice. They worked just fine.
I'd bet against "most", but who knows.
Nah, I'm sure you're right if you take it literally. There was supposed to be an implied "among people who gave a crap about their computers."
Right – their first was the Mighty Mouse, introduced in '05. It's just interesting to me that Jobs was consistent enough in his beliefs supporting one button mice that he even used one himself. His use of a computer is certainly frequent and deep enough to benefit from a more powerful mouse.
