He may have been right in theory (and where the available technology

where passive cooling is sufficient. (And the G4 Cube definitely
overheated.) Where it isn't sufficient, it doesn't work and you get
laptops that are uncomfortable to use like the MacBook Pro in my example.
... The fan controller(s) in the first Macbook
Pro were set to almost *never* turn them on. The fans ran at extremely
low speeds even when the machine was baking your pants to your legs. I
picture this as another case of Jobs' "ideals vs. engineering" (see
also: Apple III, G4 Cube) -- "This thing needs to be silent!" ...
On the whole, he was right. Passive cooling was sufficient for the
Lisa, the original classic Mac, and the G4 Cube.
And people still hate fans. Apart from the noise, a
20c fan frequently
kills a $1000 computer or a $200 video card (thanks China!)
So... buy a better fan? It'll last longer and be quieter! Fans are
replaceable, a laptop that has suffered thermal component failure due to
poor design, less so.
When critical cooling components can fail and destroy expensive parts
without warning, that's a serious design error.
When critical cooling components are left out for aesthetic reasons,
that's a serious design error.
