I often find myself messing with my Treo when I drive. On my way home from work, I was editing a Speed Dial button -- modifying a ringtone. Well, apparently traffic had stopped ahead of me.

Needless to say, I hit the brakes and hit the car in front of me.
Luckily, there wasn't any damage to speak of and everyone was ok. I've learned my lesson ---
Everyone be careful out there...
