Windows 10. The reason I switched was pretty funny - I had previously bought a cheap SSD and moved my install over to it, and installed Arch on my HDD hoping to experiment with it.
I never really did that, but one day before Christmas my computer booted straight to Arch to my confusion, and after a while I figured out my SSD failed. I ended up installing gnome to have something to use in the meanwhile, since I wasn’t gonna be buying a new SSD in the next few days, but then I just decided to stick with Linux. As I learned more about it I realised I was barely missing anything, and I preferred Linux for what I had.
Hold up, how is proton leveraging open source to avoid dev costs? Are you referring to steam using and contributing to existing projects instead of reinventing the wheel? Or to game developers that use it as a reason for not making native Linux versions, which wouldn’t be Valve’s workforce in the first place?
I can see how the things Valve does contribute to their business model - steam input giving their controller compatibility with games, proton letting them launch a Linux-based handheld, and the new recording feature probably there for the steam deck… But the thing is, Valve is still providing all those things to customers for no extra charge, and they keep adding new stuff.
