Andy Ihnatko on the iPhone mute switch:
If I forgot to unmute my phone after a movie, I’m a dumbass. But if my iPhone makes noise during the movie despite the fact that I’d deliberately chosen to silence it, I can only conclude that the dumbasses in this equation reside about 3,000 miles west of here.
I disagree here and think (along with Gruber)that the iPhone mute switch works perfectly as is.
My reason is simple: when I go to bed at night, I want to know that my alarm will wake me, but that my drunk friends won’t.
