How unfortunate that this did not turn out to be the case, and I think it's likely that is because most people liked the "simple and easy" Mac-like UIs with no learning curve, and didn't want to grow beyond them.
The point about "user control" is odd though, since that's basically the exact opposite of the Apple philosophy today, and even the older Macs seemed more opaque and with less user control than the PCs of the time.
