XtremeMac has released the first high-fidelity iPod recorder with a removable microphone for the video iPod. The MicroMemo plugs right into your dock connection port and will record memos, meetings, lectures, or any audio content directly to your iPod.
It comes with a flexible removable microphone but it should be noted that any microphone with a 3.5mm plug is compatible.
The best part is the MicroMemo requires no additional batteries as it will run off of the iPod power supply. For under $50 this is a great gadget for a person on the go.
