If I'm going to buy an iPhone controller, something slim like this wouldn't be necessary. Are most people going to carry something that long anyway? It's not pocketable. I'd rather get the model that has dual thumbsticks, per the reference controller schematics that Apple released, so that I can play 2D and 3D games. I'll probably keep it in my bag and pop it on when I need it, or at least keep it around at home for some more intense gaming sessions. I've been waiting so long for this! I have the feeling that this will really put Nintendo and Sony out to pasture when it comes to portable gaming systems. They were already in trouble before these new controllers. I think future iOS devices running 802.11ac hooked up to a new Apple TV running 802.11ac will enable even better AirPlay streaming quality with less lag than we have nowturning an iPhone into a full-fledged gaming console. I'm already pretty sure the 5S is on-par with the Xbox 360. Will the gaming performance of the iPhone 9, 9S or 10 (iPhone X?) surpass the Xbox One by the end of it's life cycle in the early 2020s? I think so.
