And like the iPhone and iPod it has very real innovations (in engineering) that people always underplay because "No wireless, less space than a Nomad, lame!", or "we had smartphones before, I had some Ericsson/Nokia/MS gizmo, so what's evolutionary about the iPhone?".
You're right. At the end of the day, they're technically evolutionary, not revolutionary, which was the central conceit of this subthread. And there's nothing wrong with that. Technical evolution can lead to consumer revolutions.
