Siri, With Headphones On

Today I learned that when using Siri with headphones on1 she will read back any text or email messages before they are sent.

From Apple,

“When you use earphones or a headset, Siri reads back text messages and email messages that you’ve dictated before you send them, and it reads back the subjects of reminders before you create them. This is especially helpful when you’re driving and can’t see the iPhone 4S screen.”

I wish this option was the default behavior. There have been numerous times when I’m walking between buildings or to the car and want to send a note without looking at the screen and I’m not wearing headphones.
