I posted this at Spymac, but I didn't get to see what the answer was, as I forgot about my question until Spymac shut down for their WOS upgrade. Anyways... What's the quality of iMac's mic? I ordered an iMac (G5, 20", 1GB RAM) but I'm wondering if the internal microphone is sufficient for audio chats, or if I should look into getting an external microphone. Also, if the internal is not sufficient, does anyone have any reccomendations on microphones that have worked well for them? Thank you!
