Not that I disagree with the good experience - Valve has done a lot to support Linux gaming and I’m bloody grateful for that, but I believe Valve was kicked up the arse by regulation and Epic Games converting their Fortnite launcher into a Fortnite launcher that lets you buy other games being a viable threat (the whole controversies not withstanding).
Not to mention that in the US and Canada (outside of Quebec), you get a one year warranty on Steam Deck while in some other places (namely the EU, UK and Quebec) the regulations kick in. For the UK, you get six years minimum from consumer protection law (oversimplification, but you get the gist). Some of their good decisions and experiences were a result of regulation forcing its hands.
