People who use Bluetooth regularly find themselves having to turn it on and off for the sake of battery life. It's great to be able to do so without diving through multiple menus.

It's also not just airplane mode - do-not-disturb mode is also really useful, and it should be fairly obvious why someone would want to toggle it without menu-diving.

Ditto orientation lock. In iOS6 is tap-tap-swipe-tap-tap, now it's just swipe-tap. This last one is kind of a platform problem though - orientation lock is useful in part because some apps excel at landscape mode, while others suck at it but insist on enabling it.
