Maybe this is all as a result of installing on my own hardware instead of a System76 laptop, or maybe due to my general unfamiliarity with Linux, but I didn't find installation and setup very easy at all.

I was installing alongside Win 10 and it totally borked my bootloader, this in itself took me quite a long time to repair.

The steam installer worked well, but I couldn't move my library to a secondary HDD. So some Googling shows I need to install from apt instead of from the PopOS store. Which I do, but then I also had to do some more Google FU to figure out how to get PopOS to mount the secondary HDDs in a useful way.

As it is now, about a quarter of the applications I need are in the PopOS store. VLC for example isn't. So while the store is setup nice it is only marginally useful.

Finally, switching audio between wired headphones, Bluetooth headphones, and my HDMI monitor has been a nightmare.

Does it run well and is it stable once I'm up and running? Yes. But the devil is in the details. I really want to like Linux, and I am enjoying the lack of forced ads on PopOS compared to Windows, but how is widespread adoption of Linux supposed to happen when this is the onboarding process?
