What kind of innovations in desktop computing would you classify as technological improvements? To me, since we created integrated circuits, we've generally been talking about incremental hardware improvements. If anything, mobile computing has actually innovated more than desktop (see ARM coming to laptops via M1 with amazing performance; integrated graphics / system-on-a-chip becoming more common in desktops).
