How would you warn the user? I was surprised by the behavior initially, but now I far prefer it. I spend far less time worrying about vibrate mode with my iPhone because I don't have to worry at night when I go to bed that my alarm will go off in the morning. There is no perfect design for this, just tradeoffs. I appreciate the tradeoffs Apple made in this case.
