No joke. I seriously don't see desktops running rich applications around anywhere, except the mini-computer / workstation use case.
Generally people are running a glorified thin terminal with a browser or putty connection to a dosbox app. People who actually do things on their own computers generally run laptops now. The exceptions are people who do demanding work loads, and they run workstations that can handle it--more like the mini-computer than the traditional office desktop.
There are public computer terminals in libraries and such, but the only reasons these are not laptops are theft prevention and the need for a large screen, keyboard and mouse.
Plus "putty connection to a dosbox app"? I have never heard of anyone doing that, and don't understand why they would. Or maybe you don't mean "dosbox" [1], but "console"/"terminal"?
The exception is things like receptionists, or other areas where multiple employees share a common terminal. But as mentioned before, those computers are basically used as stationary, large-screen browsers or thin clients for cloud applications. Email? Excel? It's been a decade since I've seen people doing that on desktops in office environments.
