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.
Ayaneo has a pretty good track record making portable gaming devices, mostly running Windows. I’m guessing “subscriptions” here is a mistranslation for pre-orders.
