Needed a cheap mic for my Mac Pro when its plugged into a display at my desk and tucked away in a drawer. Bought a 10 audio cable and routed it next to the display. Whats nice is I can use the cable for either Mic Pro or with a set of headphones to listen music off the computer. With the Mac Pro you just have to remember to go into the audio preferences and select if you want to use the audio port for sound input or sound output. Bought the app for both my kids touches so they have their own mics. Its a lot cheaper and less clutter than a usb mic!
