This is the HHB FlashMic. It a microphone with a GB of memory in it. It runs off AA batteries and depending on how you set it up, you can record several hours worth of audio with it.
Fantastic idea! Sadly, is over $1,000US which is kind of hard to explain, in my opinion.
I'll never convince Kelly Penguin Girl that I have to spend twice as much on my mic as the entire desktop computer.
