But also there's the market to consider. Macs users seem to like to sink their money into nice looking native apps which organize things.
I would add that Steve Jobs' own psychology seemed reduction-biased, for better or worse. His thought process was aimed at achieving impact through early/first principles, but the principles were those of concept, design, sensory experience, or interpersonal dynamics rather than information or engineering.
As a result, we get Think Different, and the first step in Thinking Different is thinking; I would add that due to the reduction it's more like thinking starkly. This is quite different from processing or manipulating, which were and still are very PC concepts, compared to Apple.
Anyway. A guess. And yeah, the unfortunate part of info-illustrations is that pages of them which reward different perceptual ordering/directions in each illustration are just harder to parse.
Honestly, Apple did a great jobs. They did care about their product(well, until recent buggy OS fiasco) and that attract people who value the same thing. Doesn't mean Windows people don't care, of course, but Windows always give the utilitarian vibes, the OS for everyone (especially in the old day)
That said, am I the only one finding it really hard to parse pages of illustrations? It feels like I'm stuck having to analyse every single illustration to figure out what the author is talking about and that a bit of supporting expository text is missing.
