People can buy a prebuilt pc running steamOS automagically updating itself with immutable images.

The advantage of consoles are:

- No minimum/recomended config to check and insurance that a game or an accesorry bought for a console gen will work well for that console gen. In term of game compat this is something Steam tried to with the steam deck but has no way to enforce really and the biggest one imho. When you buy a brand new "budget" computer in the price range of a console you usually knownyou won't be able to play some of the upcoming AAA titles at least woth decent graphic quality.

- availability in retail stores

- ability to sell games in the second hand market but I don't think this is something that is here to stay with the disappearance of physical medias
