UPDATE: Despite saying they were using SteamOS on the homepage, they’ve since clarified that it’s actually “an optimized version based on HoloISO”. HoloISO seems to be a community compiled version of SteamOS. It’s very similar but it’s not officially SteamOS.
Now the handheld market gets really good.
I remember when I had to use my Steam Deck connected with USBC as a “desktop” for a while. It couldn’t remember to put my taskbar on my preferred monitor no matter what I tried doing.
