Hold the phone there. Why is Windows even entering the comment section of a SteamBox/SteamOS article?
It's Linux-based, SixAxis controllers are easy to set up on both Linux and Android, Valve will have a very easy time creating a simple easy-to-use GUI for linking the two.
Windows isn't; your parent is explaining that clearly, given the 360 controller works great with Windows, using a controller with your PC is no longer quite the black art to the public that it used to be.
