He probably was referring to the Galaxy Nexus, which I assume has decent enough (probably perfect) CM support. Like you say, achieving compatibility with every piece of Android hardware out there seems unlikely, mostly because of proprietary binary drivers. I don't see how that makes CM unviable, though. You just have to factor in CM compatibility into your buying decision. That means either basing a decision on past experience (ie. based on previous models, any new Nexus hardware -- if there is any -- should be ok), or waiting a bit after new hardware is released to see how it turns out. Of course the latter option is pretty painful for most of us. It's too bad Google doesn't seem to care about any of this, though. It would have been nice if Android One devices came with guaranteed access to/documentation of the proprietary driver blobs, or, better yet, open source drivers for all components, or anything in that vein. But I think we're long past expecting stuff like that from Google.
