Good question! After installing Emulators on my Steamdeck I realized it could run as a desktop. Also, I learned it was a rolling release. This seemed attractive to me, so I wanted to hear how mainstream this could be.
Sounds like the answer is not very. Some other good suggestions in this thread I might try, though.
I think the reason why is its a powerful computer and if they dont already have a good computer, why not make this their main PC? It would be cheaper to buy a dock, monitor, keyboard and mouse (under $200), than buy another device with the same specs.
