In addition to the mentioned pinch to zoom, there is the two finger twist (or dragging one finger while another remains stationary, as a pivot point) to rotate stuff (which is handy for maps). Plus there are different gestures, like swiping with 4 or 5 fingers on iOS5 will let you jump between frequently used apps, or a multifinger pinch to close an app and go back to the home screen.
Plus, the biggest use is in games. Tablets generally don't really have any buttons, many games are implementing a pseudo controller set up, with an on screen direction pad, and buttons. If multi touch wasn't a possibility, they would have to have some sort of hardware controller to even play the simplest of traditional style video games (even Space Invaders, or Galaxian, both available for tablets and phones would not be playable).
