Such a shame that Valve isn't pushing SteamOS harder (unless I'm missing something?) because they are in the best position to loosen Microsoft's stranglehold, not only in terms of the Windows platform but also controller support. Even when games do run on other platforms, they often only natively support Xbox-style controllers. I don't think this is an accident.
