Steve at his desk
I really like this photo:

I learned so many things from it. Using the Mac Pro in the foreground as a reference for scale, I learned that Steve had a custom 60" monitor made for his home office. I also learned that he was four meters tall.
That’s probably not a Mac Pro; IIRC some of the 3rd party vendors manufactured hard drive enclosures in the shape of a “mini-me” version of the Mac Pro — which would fit with the scale.
The monitor doesn’t look quite right, but a custom 42" in an Apple Cinema Display enclosure wouldn’t surprise me in the slightest — I’m fairly sure that before prototypes would be let loose in the world Steve would insist on road-testing them himself.
