Just finished a two hour "call" with a remote co-worker in Florida using iChat AV. Last time we went over a bunch of code it was over the phone, which not only ran up a good sized bill but gave me a killer kink in the kneck. iChat enables us to paste code snippets into the chat window and send entire files while we are talking.
iChat must be doing some sort of echo cancellation, I used the PowerBook's built in mic with the audio coming from stereo speakers less than a foot away. Good audio, hands free talking, no discernible delays...excellent. Still, I'm tempted to get an iSight now.

No kidding! Me, too. Systems Plus (local computer dealer) is planning to use one on a Powerbook carried around the Home Show floor, transmitting to a base station at their booth. Cool stuff!
