Some iPad owners might not be aware that the original model has a microphone built-in right next to the headphone jack. Both the 3G and Wi-Fi only models have a little mic hole in the same place on the iPad's metal top. Now that the next generation iPad 2 is designed for use with Apple's FaceTime video chat software, the internal microphone is getting some more attention.
Tests have indicated the iPad 2 Wi-Fi only model captures higher quality audio than its 3G-enabled cousins. Pictured above, the two microphones were tested by iLounge in their comprehensive iPad 2 review.
