Just remember that these accidents are not the fault of the iPod. It could have just as easily been a Sony WalkMan or suchlike.
(Don't you just live the walkman brand?)
Tom mentioned in the 2/15 podcast about an Australian woman who died in a bicyclist v MVA accident in London, and her use of an iPod was implicated in the death. Here is another one:

Evidentally, this student at McMaster University was walking home at night and was hit by a truck that was spreading sand and plowing snow. She died at the hospital. An iPod was found at the scene, it is unclear if she was using it at the time.
As V (correctly) pointed out wearing any kind of headphones when biking is dangerous (and illegal in some areas, is is illegal everywhere when driving). Even when running (which I do) it is a little dangerous (as the story points out). You can get lost in your world, and no not have adequate situational awareness.
One warning to women especially. Women who run/walk, especially on jogging trails, are easy prey to attackers. Running alone is bad enough. Running alone with a personal music player (or radio, or whatever) is almost insanity. These creeps can get right up behind their victims, and they don't even notice.
