At least the boomerang curved into your palms. This literally curves away. The only part of your body that will be holding onto this "prototype" when you use its joysticks are the tips of your fingers.
From what I’ve read, the boomerangs ps3 controller wasn’t actually dumb at all. It was apparently extremely comfortable to hold because of the way it curved into your palms and the placement of the buttons and sticks felt really natural. But the poor reception to the look of it basically bullied Sony into reverting to the classic DualShock layout.
