The Steam Deck also capitalizes on the heavy investment Valve has done in the WINE ecosystem over the years (e.g. Proton). As someone who has been using the fruits of this for years before the Steam Deck came about, I was in awe when I realized just how long they had to be willing to continue on this path without obvious external benefits before they got to this point. In my opinion, it's an amazing example of how a company investing in an open ecosystem can benefit both compared to the usual zero-sum exploitation that I'm so used to seeing.
