Cons
Con Not built around the desktop experience
SteamOS is, first and foremost, meant to act as a gaming console - it doesn't ship with even some of the most basic applications, such as a file manager or image viewer. As a result, using SteamOS as your primary operating system would require a fair bit of work.
Con Hard to install
If you've installed Arch you're probably fine, but for those used to simple installs like (Ubuntu to name just one) you should prepare some patience, determination, and painkillers. Good news is, it's getting better (it's very young).
Con Difficult to install on non-free hardware
Unlike Debian, Devuan offers no unfree netinstall media, so if your system needs unfree drivers (e.g a laptop or a tablet), you'll have to download the Debian firmware on a separate USB.
Con No systemd
Con Fragmentation
Forked distributions like Devuan and Artix fragment the Linux community and hurt the original project. Debian users who do not want systemd should use Slackware or BSD instead.
