Cons
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 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 Not visually appealing
The operating system is not very pretty.
Con Can be somewhat slow to turn on
Once it is up and going it is unrivaled in speed, but it can be sluggish when it comes to turning on, restarting, or turning off.
