I have read here that charging your ipod in a case can be a very bad thing. But I have an hour commute to school and have always used an auto charger. I will be playing music while my G3 ipod is plugged in to the charger--is this a problem? I have an Action Jacket, and while it is great for my morning walks, it would seem that the case would hold any heat quite nicely. I got the case free with the ipod, so replacing it would not break my heart.
