Anyone notice n the keynote today when Steve was demoing multitasking in 4.2 on the iPad, the orientation lock button from the iPhone in the multitasking bar was there?
Well the iPad already has a hardware switch for locking the orientation. If they add a software button then the switch will keep reversing itself (the orange "locked" state will become the unlocked state if you press the software button and vice versa).
So either they're going to remove it before the final release, or keep it and add unnecessary complication/confusion.
