Xbone was my last console purchase and I considered it terrible value for money. AAA games aren't generally worth looking at due to their monetisation strategies. Console wars are anti-consumer. Indy titles, what I mostly play don't have the same availability. Steam workshop has no equivalent on console. Multilayer is a paid addition, not that multiplayer is worth it because the multiplayer games have the worst monetisation strategies. I could go on.

But you're right, that's what I want, a Steam Machine.

I have a console and still play most games on the steamdeck. A lot is portability, but other times it's what games are on PC vs Consoles.
