I’m considering purchasing an iSight from Apple using some of the proceeds from both a web coding project and temping. It would be helpful for remote collaboration on web work (my brother lives in the boonies). The reviews I’ve read thus far have been very positive. The only downside most people mention is the current lack of cross-platform conferencing using iChat AV. I believe Apple is using SIP (at least for VoIP), so it should only be a matter of time before some enterprising soul(s) make(s) it happen.
