The Steam Deck is a full PC that boots into a console UI. You can switch it into desktop mode which uses KDE - a very popular desktop environment. You can dock the Stem Deck using a USB-C hub to connect to a monitor, keyboard and mouse. This is a use case that is supported by Valve and Valve sells a first party docking station to facilitate this. There have been multiple people citing on the Steam Deck subreddit that they regularly use the Steam Deck in this way and a few even saying they use it as their daily driver. It's a laptop in a handheld form factor. That is all.
