It’s also a fundamentally different user experience. Sure you could load SteamOS onto a machine you built. But the point is that this targets the couch players, instead of the desktop players. And very few PC players will build a new PC just for their couch.

I love my Steam Deck, because it has caused my wife’s complaints about gaming to dry up almost completely. When I’m at my computer desk, she can’t snuggle with me. But by moving to the couch, we can snuggle while I play. Her complaints weren’t really about my gaming; they were about my physical unavailability. And the Steam Deck allows me to access the vast majority of my PC games on the couch, so we can both be happy.
