The beach head is already there, steam deck. All it takes is one gaming generation growing up with freedom..
Are most Steam Deck users even aware that there's a Linux and some userland under the hood, or is it just a portable game console to them (as an Android phone is just another pocket computer)?
I could be in a bubble, but it seems like even the less technical Deck owners can at least follow Reddit or YouTube tutorials (of which there are many) to do more advanced things on their Deck. Setting up emulators is one of the more common things people do.
The OS also comes up in comparisons to competing PC handhelds, as the marginally more powerful alternatives all seem to come with Windows and suffer in the UX department. Valve allegedly plans to release their current SteamOS version for others to use, but it hasn't happened yet. There are a couple third party recreations in the meantime that people put on these other devices themselves.
