SatyrSackSteamOS has been out on Steam Deck for 18 months, but still no general release in sight. I wouldn’t hold my breath. I think we’ll just have to continue to make do with the likes of ChimeraOS/Nobara.
BananaTrifleViolinTrue. There is an unofficial release - HoloIso - which uses Valves packages but is not quite complete. Also manufacturers may be able to get access as Valve previously has been keen on getting other manufacturers to buy into it's hardware attempts (e.g. Steam PCs previously, and VR now) but I'd expect the manufacturers to be making a big deal of it if they were launching a SteamOS handheld. It seems Valve want to keep exclusivity on Steam Deck for now (which makes some sense given how successful it's been)
(which makes some sense given how successful it’s been)
It really doesn’t make sense, considering how small the profit margins probably are, if any.
What would make sense is making the Steam-first OS open to be installed on any device.
