SwitchEasy has introduced its new ThumbTacks Micro-Microphone for the iPod nano 4G, iPod touch 2G, and iPod classic (120GB). Designed to look like a slightly-oversized push pin, the ThumbTacks features an integrated microphone, and a 3.5mm jack that plugs directly into the iPod, allowing users to make audio recordings with the built-in application. Available now in black, white, or red, ThumbTacks sell for $13.
