SteamOS is fantastic for someone like me who wants a pc gaming rig that just plays games. I want it to be functionally a jacked up console. I don’t have time to sit around tinkering and dealing with drivers and all that. I want to set it to auto update, leave it in gaming mode (big picture mode on desktop I guess?), and just enjoy it.

Consistent support by a quality, professional, largely well-behaved company. Less bullshit, less tweaking, more of a “it just works” experience. The moment an updated steamOS properly drops for desktops I’m building a PC for it.
