I've never met anyone who said it was, so I doubt it. Stop being a blind advocate and realize that some people do need Windows because they need apps that only run on Windows.
It's a trade-off. In my grandpa's case, he would love now to give up Photoshop in exchange for freedom from a litany of Windows nuisances (viruses, registry issues, major UI changes - things many of us forget about that use OS X or Linux). Unfortunately, that ship has sailed; he's 93 now and while not necessarily senile, he has real trouble grokking the cloud and therefore Chrome OS is prohibitively confusing.
