I have a stereo microphone with a line in jack built into it 
that I can plug into the bottom jack on my iPod. It makes 
surprisingly good recordings to WAV files of lower-volume 
sources, though it completely blew out trying to record a 
live band. I bought it at Wal-Mart for about $30.
I haven't used it for any interviews, but I would think it 
would work pretty well.
I see some mixers are starting to incorporate iPod slots, so 
you can do your recording on it.
