I just talked about using it on Desktop mode like a PC. I never said anything about doing business on it or using it as your Work PC.
Even the announcement "trailer" of the steammachine showed it getting used on a Computer monitor with mouse and keyboard in desktop mode. They even said they want to improve the "Desktop mode only" experience iirc and for there more apps than just games are important.
And i personally probably wouldnt have bought a steamdeck if it wasnt possible to just go into desktop mode and do whatever.
