Shit, even those who do know Windows will find it daunting.
I just bought a PC over the weekend to replace my PS5 (because fuck Sony) and I installed SteamOS onto it.
I am having a hell of a time figuring it out. It's such an alien OS to me as a lifelong Windows user. I'm still trying to learn how everything works, like udev rules and the file structure/hierarchy it uses. It's mad confusing, normal/less tech savvy people definitely wouldn't be able to handle it.
