As mentioned above, user profiles, app locks would be great. Especially for an iPad 
Though gestures ( simple ones like swipe up, down, right, left, long hold, tap, double tap etc. ) would also be good additions to iOS. Toggling Wifi, Bluetooth, starting apps, locking the device, quick messaging etc... There are many possible benefits.
