Yeah, if you're smart about these things and know where to look and don't mind some diy, an adequate desktop can be found for $200. A game streaming service would be perfect for that sort of setup. But I still think the price point for streaming is wrong for mass adoption, and for anyone with even minor gaming interests already (e.g. you've bought a decent amount of games over the years) then being able to use your existing library of games is an essential feature.
Wrong subthread, small apartment isn't regular travel ;)
But I don't think there's need to argue this further, I think the point that there isn't a one-size-fits-all solution has been made exhaustively, by everyone.
