Actually Sony does have a monopoly on the Playstation market. A monopoly is not in itself illegal. The first question is whether Sony has used that monopoly illegally or defended the monopoly illegally. Second, even if it has, the question is if the harm caused by it is worth even pursuing Sony.
Most likely neither are true for Sony but even if it is, it should be self apparent that distorting the smartphone market, or even the iPhone market, devices which are almost essential parts of modern day living can cause orders of magnitude greater harm than anything Sony could do in the game console market, which is much smaller, much narrower, and far less important.
And all this ignores that the DoJ's filing is about antitrust issues beyond just monopoly issues.
Best shot yourself in the foot argument so far. Sony Entertainment is actually bringing the controller and the games to pc. The controller's unique features are also actually usable
I get the point, but it's watered down by your example which isn't true. I'm happily using a PlayStation controller on everything _except_ a PlayStation.
