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.
That makes more sense actually. Well, either way it is good news for Linux, hopefully.
