When I finally put a stake in the heart of the SCO UNIX system that hosted our legacy accounting system, someone commented "so I guess UNIX is dead now, isn't it?" Then I pointed out that our server infrastructure was still Linux-based, and that the Google Apps we used ran on Linux, and that the NetSuite ERP system we use ran on Oracle Linux, and that the few macs we have were BSD Unix-based, and then the iPhones, iPads, Android phones, Android tablets and well, pretty much everything except the Windows desktops were UNIX-based. I think they were more confused rather than less after that explanation, but it felt good.
