I mean, you do you, but I do plenty of actual work on my Arch machine. I've been working on an album, which involves not just the recording, mixing, and mastering, but also there's a bunch of paperwork involved in the business side of things, not to mention stuff like album art. I game on it as well, but saying Arch isn't good for work is just ludicrous. It's a DIY distro, you get what you put in. A few basic steps can keep Arch just as stable as anything else.

That said, my server is a Debian machine, but that's because my services don't need up to date packages, and I just wanted something I could stick in a corner and forget about.
