I think the mouse is critical with non-touchscreen interfaces. Smaller hit-targets, lots of on-screen buttons/menus, file manipulation, etc. The more and more modern desktop OSs evolve, the less of that is required. I want to open a file? I search for it using Win key / Spotlight - I just need to know the name or content. The day will come when LLMs come integrated with your desktop OS and abstract away even more of the screen elements and interactions...
