I don't entirely agree with that characterization. I believe Plan 9 offers fundamental technical advantages that would interest a small but significant and sustainable population of users and developers, and that it's not the inertia of other platforms that it can't overcome, but itself. Its user experience is utter crap, a combination of poor/lack of design and annoying idiosyncrasies by certain of its developers. It's a research platform, and no real effort has been made to turn it into something more practical. If someone were to pick it up and turn it into something people wouldn't hate using, I think we'd see a community on par with NetBSD or OpenBSD.
