Hokey indeed. The built-in MP3 player is, in my opinion, a major design flaw. Everybody knows that a chick listening to music and tuning out the rest of the world makes a prime target. They're just encouraging lax behavior instead of reinforcing situational awareness.

I can't tell how big it is, but purse space is often at a premium and designers need to keep size and weight in mind. It is easy to get a chick to carry pepper spray precisely because the units can be tiny.
