The god honest truth is that what many users really want for desktops is the incredibly range, freedom and customization of the PC enthusiast hardware ecosystem and MacOS. Not specifically high-end power.
"Professionals" spend thousands of hours with their tools and the tools need to fit their personal quirks as that allows them to feel the most productive. A handful of hardware offerings that Apple prefers won't allow for it and the market is too small and too long tail for Apple to even care.
The custom hardware market lets pros assemble specifically the things they need to be productive and to rebuild at will whenever their work needs it.
The Mac Pro is a good shot in the kind of direction that pros need, but it really will only intersect with a percentage of users.
