I agree that it works well.  A couple years ago my then 13 yr old son, 
Jonathan kb3rli, and I used it as a chance for him to learn some 
electronics because he wanted to key the rig with it.  We used 2 op amps 
from a quad op amp chip to make an amplifier and a comparator.  The ipod 
audio was amplified and compared to a voltage.  Output of the comparator 
went to the gate of an npn transistor to key a rig.  So he used his jail 
broken ipod (no iphone for a 13 year old!) to key the rig.  We also used 
only one value of resistors so he could learn about series and 
parallel'ing them to get an equiv value.  Maybe overkill to use an ipod 
as a key, but it was a fun project!
