And yes, this was apparently Steve Job's idea, as he felt that fans were "too noisy and inelegant". I imagine that he felt that fans were holding humanity back, and smugly told people who disagreed that they were clinging to obsolete technology.
It got so bad, that Apple actually advised their customers to physically lift and drop their Apple IIIs to re-seat the chips that had popped out from the excessive heat.[2]
Of course, if today Apple decided that fans were obsolete again, and the latest Macbooks were twice as heavy and still overheated, then it would become the new normal, and it would be hard to find computers that had fans anymore, and we would long for the days when we could just use computers for as long as we wanted without worrying about them overheating. And on the internet, commenters would say that it wasn't a big deal at all, and if you were some sort of power user that wanted to use your laptop for more than a few hours at a time, you should buy a $250 cooling pad for it.
