does anyone else agree w/ me on this?
Nope I don't agree on that either. It's the driver construction, period.

Impedance alone doesn't tell you everything as I described in a previous post.

I thought about that and I came to the conclusion that this is wrong, at least (or especially) for portable devices.
The voltage of a portable device is limited, yes. But with <100% volume it's very likely not to produce distortion with a high impedance load connected.
Low impedance loads on the other hand can be a big problem. We've seen that with certain ipod etc. measurements that quite a few devices have problems powering low impedance (like 16 ohm) head/earphones correctly. Often the resut is rolled off bass response and other FR variations, distortion and so on.
To make things worse, some IEMs have impedance dips that go down to 10 ohm.
With headphones you don't have such problems, especially not if their impedance is higher.
