If the iPad is just a big trackpad that moves a pointer on a remote screen, we’re in for a very boring future.
It’s something you definitely see if you have both iOS devices and children, both areas where my household is well equipped. The touch UI works extremely well when you are looking at the device. Not so much when you are not.
