This has more point on the iPad than on the iPhone. The iPad is big and heavy, making it much more of a chore to reposition/flip it in order to find/press the button. It's also very easy to hit the button by accident. Double-clicking to switch tasks is especially difficult. The weight and size makes it very hard to get the right muscle tension to press the button rapidly. I often press it too slowly and get the home screen instead of the task bar. I'm surprised that Apple even released it this way. Maybe the long delay bringing multitasking to the iPad had something to do with this.
