I didn't read any of the context around that comment, but to presume that it will run on 'anything' is silly.
It won't. It just takes too much hardware to do these things...
The base UI framework is designed around a 3D/Holographic style that is seriously processor intensive.
http://www.linuxinsider.com/story/Whats ... 1295064006It's the hardware vendors who have to put together packages to support their products, and the framework is optimized around the Tegra 2 as that is considered the baseline for 3.0 hardware deployment.
That isn't to say that no one will put together a stripped down package that will run on a 600Mhz/800Mhz/1Ghz single core processor. Just don't expect it do much in terms of features.
I'm quite comfortable saying that most of the hardware in mainstream distribution right now will never see honeycomb (outside of the mod community, where interesting things are possible).
Ninja Edit:
In fact, I would bet you a nice lunch that even the early Tegra 2 devices (like the LG Optimus 2x) may not ever see an official honeycomb release.
