Agree on the exclusivity thing and also I'm one of those with big backlog; it grows faster than I can play. There is no need for me to buy day 1 expensive AAA games. I disagree with all points made in the last segment of your reply.
Also windows 11 isn’t terrible… It isn’t good, but it’s fine.
Windows 11 is in my opinion terrible. The updates, the spying, the bloat, the UI, the ads, can't customize much... I don't like anything in Windows 11. And it gets in the way of playing games too, especially if you want to play with gamepad all the time and messages appear (Steam Controller however helps a lot here). To a point that I will never use Windows 11 on my own computer ever. (and it's not like I wouldn't have experience in Win11 too)
And I don’t think I agree with it being cleaner to boot up a console and just play a game.
If you ever used SteamOS through Steam Deck in example, then I think you would agree with me. Starting Windows requires a password entering, which is not an issue with consoles. Then Windows loads lot of crap and bloat and you might use the computer for other stuff than gaming too. Here and there are issues using it to play games, like updating drivers, configuration and so on. Playing games on a console is much cleaner and simpler than Windows 11 on PC. SteamOS is also cleaner than Windows 11, but consoles still a lot less problematic in regard that.
If you have steam run at start up, they are pretty equal.
They are not. Running Steam in foreground in Big Picture mode is just not the same. It looks the same on the surface, but there are lot of little issues.
