The main problem was the missing second stick. It was well built, but for game where a controller is nice touch pads sort of suck compared to a stick and for games where a mouse is nice touch pads sort of suck compared to a mouse. So the only real advantage a touch pad brings is in an environment where you can't bring a mouse. I really liked the extra back buttons. with two sticks that is where all the face buttons should be, on the back.

Somewhat related, but I enjoy the topic. Is how freakishly good the mouse is for FPS type games. If you asked anyone to design a purpose built controller for a first person game they would not come up with a mouse. But somehow despite all odds that thing designed for moving a cursor around the screen is the best controller yet for looking around. Probably something about the huge throw distance compared to any other controller.
