Lol at everyone who thinks that Sony should make a Playstation phone. There is zero need. It would only serve to lose them even more money on their mobile division.
Of course, many of the people advocating it just want Sony to make them their dream phone rather than actually focus on the logistics of developing such a expensive device only to appeal to such a limited audience.
Actually PS brand is wasted if it's just sitting on console platform. Sony need to learn from Apple
