Desktop is still better than mobile at nearly everything. The screen is bigger. A cursor is more exact than a finger. The keyboard is 200x better. You generally have more storage space, and it's easier to navigate. You can emulate other systems. Most messenger apps also exist for desktop. You can try different operating systems with minimal risks of bricking something. Spotify Free is actually usable. Really the only advantage of a phone is that it's small and light and you can carry it everywhere. I almost never use my phone at home except for actual calls (and you can make calls over desktop too btw, it's called a softphone and I have never found one that works well for Linux ahaha).
