I don't often post about gadgets but this is lovely. Belkin's TuneTalk is a microphone that snaps on to the top of your iPod. You can record podcasts straight to the iPOD. It even records in stereo, using sound from two mics, tilted slightly away from each other to create stereo effect. It then stores these files in a dedicated directory on the 5G iPod, the 5.5G iPod, or the latest iPod Nano.
At $69 it's fantastic value.
