I'm sure it's perfectly possible but some people don't want another thing to configure and troubleshoot if that's their day job.
You might get your PC setup to do almost that, but it will require tinkering with keyboard and mouse to update OS and install games. It's not what I want when I get home. The console occasionally have issues too, but far far less often than PC in my experience.
100% this.
It gets even better when you realise that modern consoles support sleep too. You can go from "off" to "exactly where you were last night" in a matter of seconds.
I say this as a primarily 95% 3+ decade PC gamer. The other 5% goes to Nintendo exclusives such as Zelda or Mario.
I don’t want to setup and configure yet another computer.
I have consoles and a powerful gaming PC. I use both regularly. For me they’re good for different things.
My Nintendo Switches get the most use.
Once you buy a prebuilt machine you're losing a good chunk of the savings that people talk about when buying a PC. You also don't just install steam, you have to install drivers, and maintain an OS (which doesn't have a controller friendly input method) so you need a keyboard and mouse around for windows update time or driver update time.
You mean you buy them from Steam, you launch a third-party launcher from Steam and launch your game through that launcher. I know that at least EA and Rockstar force you to use their launcher even if you buy on Steam and Microsoft also requires you to have Xbox stuff (at least for Forza Horizon).
You’ve just demonstrated one of the reasons people get consoles.
And you can always run this the other way around: All modern games that run on console and PC support controllers on PC. It's games that are very old that sometimes need a manual intervention. BUT consoles can't even play those games at all, so they basically have no controller support too, just with zero recourse.
