PopOS has been working well for me so far. After a couple of weeks of messing with it to fix some issues, it works seamlessly for the most part. Every so often I find something new though. On Windows I could easily plug in a second pair of headphones and switch between them as outputs. On PopOS it doesn’t work this way. I looked up a fix, but I saw that it will require changing more settings and probably installing some more packages, so I decided not to bother for now, lol.
I will say that I’m not a fan of the weird pop shop. It feels janky to use, and sometimes the gnome software center gives me notifications to install updates when the pop shop also can install those updates. It feels like there should just be one place for updates and new apps by default.
But the steam network is still around. When steam actually shuts down and no longer has the infrastructure to provide downloads for games, I have no idea what their plan is. They hypothetically could provide a way to remove the DRM, but I doubt that it’s something the publishers of games would allow.
