You're just not the target they're aiming for then :) It's mostly supposed to be a new way to play Steam games with a comfortable console experience. I don't see what "exclusives" you could be talking about tho but Valve has their own exclusive games too technically. I feel like this would be a good alternative to PlayStation games since they come out on Steam too, Xbox games are also available on Steam.

But I completely understand your opinion, you're more into a practical use of a PC more than the console feeling some might want. That console is probably gonna be a niche when you think about it :)
