I've since upgraded to the new Kodak zi8 camera (available from Amazon.com for about $180) which is just amazing. I can't say enough good things about this camera.
It has an external microphone jack (which the zi6 did not have) and it uses a rechargeable battery that can accept an external power connection during filming (meaning battery life is no longer an issue if you're near a plug, or if you're not near a plug, you can use an external battery pack like the Tekkon external battery pack, which uses 4 AA's).
At left is a picture of me using the zi8 along with the QuikPod to capture the content of a panel at a Digital Hollywood conference.
Here is a sample panel that was recorded with this camera (may take up to 30 seconds to start playing):
