Games

Do you realize the difference is that a console will generally give a known quality and they usually just work without tweaking and tinkering?

The problem with this argument is that it only applies to PCs that you buy and build from off the shelf parts like any other computer you get where everything can be different. It does not apply to a pre-built console type PC manufactured using a custom IC pre-configured operating system dedicated to run games in a console-like experience, where every single one of those models are the same, especially in a case like the steam deck where it's made by the same manufacturer.

But not everyone wants to do more than plug in, update, and play.

Pretty sure you don't need to if all you want to do is play games, a good majority of games work out of the box already. Maybe it wasn't the case in the beginning when proton was younger (which is where this mentality comes from) but it certainly does now.

Edit: Hmm Downvote with no response, that plus your username tells me all I need to know. Have fun.
