Scott Rose gets it:

[…] going through 4 time-consuming & manually intensive tasks (double-click the button, swipe with your finger to the right, press the orientation lock, double-click the button again) is a REAL pain in the ass for something that used to be as simple as just touching a button on the side of the iPad.

And if you’re locking the screen orientation 100 times a day, you now have 400 extra tasks that you have to do every single day.

What a pity Steve Jobs doesn’t get it. There really is no excuse for Apple not enabling users to choose how this switch is used. Make mute the default—I don’t care. But wrecking the functionality of a switch millions of iPad users use daily for a function the majority will never need is just bonkers.
