I don't think it's easy to communicate the "Just Works(tm)" aspect of it. Any amount of messing around for any reason is too much. No matter how hard I've seen anyone try, they cannot match the console in that aspect. Pick up the controller, press a button, and off you go.
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'm sure it's perfectly possible but some people don't want another thing to configure and troubleshoot if that's their day job.
