I don't read the term "dual opposed heads" as 4 heads at all. I read it as two heads on opposite sides, which I believe is how the Twiggy drive operated and the reason it had two cutouts on opposite sides of the disk from each other. So I would propose it is a matter of semantic inference.
Also, I would point out that Apple is not the only computer company that spent years pounding its head against a wall trying to secure a monopoly with proprietary technology, nor the only company with the not-invented-here mentality. I would be surprised if the only reason many of the PC standards exists is because IBM established them by sheer volume of sales, but failed to secure any proprietary technology that led to their decline in market share at the hands of other PC clone makers. In fact their own ill-fated PCjr, and especially PS/2 system come to mind, when they finally woke up and realized what Microsoft in particular had done to them. And speaking of banging one's head against the wall, how long did Microsoft cling to DOS as the foundation of their operation systems when the entire industry was clearly moving toward UNIX? That's what standards will get you.
This talk of "industry standards" is disturbing. I detect a theme here which is, don't buck the system, go with the lemmings to the cliff edge if that's what everyone else is doing. Don't try to do anything new, since it will only sacrifice profits. Microsoft took that route and as a result are left holding a monopoly on a legacy bag of standards with pale imitations of other successful consumer tech products, which not only seem to be the wave of the future, but one which Apple is leading.
