And while Mars and supercomputers are cool and important for society and humanity in general, there is also no denying of the immediate impact that Windows has in most human-interfacing applications.
Supermarket checkouts, public services, small-scale logistics, health, just plain old office workers, and so on.
An undeniably large slice of companies and public sectors that do not have a dedicated IT staff rely on Windows-based computers to organize and operate their activities. Outages to those probably have more direct impact on actual everyday people going about their lives than an outage in a Mars rover or lack of WiFi access.
Just to be clear I'm not playing teams here, *nix-based systems are ridiculously important too, but the open-source base is arguably a more - democratic? healthy? stable? I lack of a better word - development process, and its importance does not lessen the importance of other systems.
