Can't you plug a mic into the ipod - probably called an imic?
I use a minidisc recorder for that kind of stuff - the Sony BZ 10. You push the red button and it starts recording. No menus to deal with. Built in crappy mic. Built in crappy speakers. Just like having a crappy cassette deck, but recording to minidisc. The advantage is, every time you record, you get a new ID#. Plus you can add ID#'s while you're rolling. Then you can go back and log all your ideas by ID#. No more fast forwarding to find stuff. Sure it's obsolete technology, but it works. Plus, if you're really into it, you can plug in a little Sony stereo mic, or use line inputs to capture signal from a mixer. It records 160 minutes in mono or 80 in stereo per disc.
