As discussed on Kotaku, Steam Deck is a perfectly usable Linux desktop computing device. While driver support is not exactly the same as a normal computer, you can install other operating systems, including Windows. The only USB-C port can be a bit limiting, so hubs and docks will be your best friends. A surprising number of common applications run flawlessly on Linux, so you’d be surprised how much you can get with SteamOS alone.
Be sure to check out our guide on how to get the most out of your Deck as a PC, as you’ll need to enable some life-saving settings to make the whole experience more workable.
