I have a Steam Deck and I’m happy with it too, but my point is that the game compatibility would just get even worse if you add on having to emulate x86, because it’s not like x86 emulation would be perfect right away, and the amount of native ports will become even smaller than they already are
Even if the architecture is an improvement, in practice it wouldn’t make any sense right now, and I can’t see an ARM-based Steam Deck or whatever selling nearly as well as the existing x86 ones given the downsides it would present
That’s not mentioned in this specific blog post, but that’s always been one of Vanilla OS’s defining features, it’s “apx” package manager to install those various types of packages
It’s even using Distrobox actually, but the point is to make it simpler to install packages for those contrainers, with the user not worrying as much about managing the individual containers, and not having to memorize the specific commands for each individual distro’s package manager
Basically, like the rest of Vanilla OS, the point isn’t that you can’t do this stuff elsewhere, it’s that it’s trying to make it easier to do it
