Oh, I hadn't appreciated you could play Call of Duty and other headline games on Android.

Which is about a relevant as the price of bottled air because 

a/. Android is doing fine witch out being able to Run Call of Duty

b/. If the Steam Box is a PC then there is still the option of running Call Of Duty if you want to. I don't imagine that Steam are going to stop you running Windows on it.
