I've been playing with Arch recently (is it ok to say arch instead of arch linux?) I installed the kernel and then... not much. Spent some time googling what to do with Arch once it's installed. "Could this be better than my Windows setup?" is the question. Not just "equivalent" but "better" such that "this is so good I abandon 3-5 cherished Windows-only apps"

Instead I waded into a soup of X11 vs Wayland, endless bickering about which tech stack, WM vs gui, etc. I would be curious to hear what people think linux's 'killer app' is. Not just "equivalent" but better. To your point, Linux needs a killer app, not just equivalent-app or "linux flavored" app that does the same thing, a DAW, a font editor, a GIS app, something.

If the best coffee comes from one coffee shop, naturally you go inside there to get the coffee. We are talking about an app so good it makes you want to install linux.
