A lot of Windows users do consider themselves power users even if they have minimal knowledge of other platforms. For example, it's quite frustrating to participate in PC building or gaming communities where every schmo thinks they're an authority on computing.

I think this too will fade with time as gaming moves to the tablet/other platforms. My prognosis is that the only people using desktop machines in the future will be scientists, professions performing heavy computing and programmers/developers.
