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.
Given how many handhelds Aya Neo has been releasing lately, I have my doubts they’ll be able to offer a polished Steam OS experience.
