To alert as many people as possible that ipods CAN catch fire during charging.  See howstuffworks for some history.  My daughter's flat has smoke alarms & I believe this saved lives, contents, & buildings.  And then only because the ipod was on a clear desk.  Had the fire involved sufficient paper or soft furniture, then it may have taken more hold & done so faster.
Please feel free to suggest methods of publicity.  I am starting with notifying NZ Fire Service.
