I spent some time today trying out iChat AV on my TiBook 500. The audio was fairly poor with a lot of background noise on both ends. The video didn’t work much better. Forget putting an AV connection in the background, the mac grinds to a halt. This could be due to Comcast, they have been sucking lately.
Thank you Apple for putting sign off messages in iChat windows, and for the auto-growing text input field!
