Personally I think this is what has held Pads (and iPhones) back from becoming better at gaming: sometimes a PlayStation style controller is just way better than touch controls on an iPad. Touch controls often don't register with the same reliability as physical controls and it does not have any physical feedback.

Apple should have made a standard gaming control that all games could use.

But the Playstation controller is a (de facto) standard gaming control that all games can use. They just let Sony make it.

(IIRC though Xbox and Nintendo controllers can also be used.)
