Got my iSight
I got my iSight yesterday (thanks to my boss!) and got a chance to try it with a friend who was in Vermont at that time (I'm in France). It worked very well! There was a bit of lag a couple of times from my P.O.V, but really not much. And my friend didn't see it.
The only thing that disappointed me so far, with the iSight, is the stand they provide for flat monitors: The back of my Studio Display 17" is not really flat, but the stand they provide for it has a flat base covered with "glue" that you have to paste on this rounded surface. So the contact is very bad but still, once you pasted it, it's very hard to remove (obviously, you're not supposed to remove it at all). I would have preferred a stand like the one they provide for PowerBooks, that just clips on to the top of the screen!Except for that detail, I'm very happy with the iSight. Update: If you start a video chat and your buddy can't hear you, tell him/her to quit and re-launch iChat.
