It appears the Air uses a similarly lower end video camera. There is no resolution specification supplied, but it provides a visibly softer picture in iChat, and oddly enough, it does not work in Photo Booth at all. When launched, Photo Booth indicates no supported camera is installed. Hopefully this will be fixed shortly, as its a bit odd to ship a new model with an "iSight camera" that doesn't do what customers would expect from an iSight camera.
