I hope it does because the biggest problem for handhelds like the Ally is the atrocious experience as soon as you leave steam big picture. Armor Crate is buggy as hell and trying to click anything in windows with the joysticks is not fun. Not to mention the usual Windows shenanigans of “update every damn day” and “spam me with bs about one drive and angry birds”.
I don't think SteamOS is a good desktop OS. It's designed for a gaming console, e.g. a handheld or gaming pc connected to a tv.
The desktop mode is great but the immutable filesystem isn't good for installing of system level apps that are necessary for day to day usage. E.g. kernel modules for OBS virtualcam, VirtualBox and similar.
Any Linux distro with Steam is a generally better experience for desktop usage. SteamOS is big picture mode by default, a desktop OS should open the desktop by default.
That's why I think people will be disappointed if Valve releases SteamOS for any pc.
The temerity to repeat 'soon' for well over a year is one of Valve's worst traits. One wonders if reflexively lying to customers is intentionally baked into their culture.
@Fubarberry a bit of newbie on these distributions, it seems that nvidia graphic cards are a nogo for chimeraos and holoiso. Has anyone some good experience with bazzite ?
