So the "defense" as I read it boiled down to: 1) Just because it isn't ready yet doesn't mean it won't be someday, 2) It has a better chance of being improved because it's closer than other Google projects to their company's core competency, and 3) The market may not be ready for it yet. Even if I grant the first two, that last point is problematic. While there are plenty of people who like keeping their data in the cloud, I get the impression the Chrome OS use case is for people who only want their data in the cloud. I wonder how many machines that will equal, given that we've just had a couple of decades of laptop usage and having more than one computer is popular. Tangentially, at the risk of sounding like a 2nd cousin to rms, I find I'm still a trifle irked that Android and Chrome are being referred to as operating systems when in fact they're new user interfaces stuck on top of Linux.
