O'Reilly posts iPod microphone shootout
The $50 iTalk Pro offered one-touch recording and three input levels but its built-in microphone picked up a lot of hard drive noise. The $60 MicroMemo used a handy boom that avoided picking up iPod noises but had no level controls and could only record mono audio. The $70 TuneTalk Stereo offers a USB port that allows you to record while your iPod is docked and charging but had stability issues for positioning and the microphone, like the iTalk Pro, picked up iPod hard drive noises.
