Afaict the "desktop" target is meaningless these days. Desktops aren't really a thing anymore in the general sense are they? Only folks I know still hanging on to desktop hardware are gamers and even those I see going by the wayside with external video cards becoming more reliable.
"Daily driver" is probably a better term, but everyone's daily usage patterns will vary. I could do my day job with a VT100 emulator on a phone for example.
The "desktop" market includes laptops but excludes servers, phones, tablets, etc.
There's a zillion office workers that have low cost mini PCs from the big OEMs on their desk. After all, all those off-lease mini PCs on eBay that are so beloved by home lab enthusiasts have to come from somewhere.
