Forgive my "technological ignorance" but I'm very impressed by the speed of the iPad OS... I will give you an example. On my iPhone, when you opened and closed apps in quick succession, or even if not in succession, it would "hiccup" sometimes and the transition from the app screen, to the shrinking app making way to the dashboard, wasn't very instant. With iPad, you can enter and exit apps one after another and the transition to home screen is so quick! Also, even things like menu navigation, is fast!!! Why?
