I was just posting a video to someone's profile on facebook, and noticed that one of the options on the video selection in flash was "IIDC FireWire Video". I selected it, and low and behold, it activates the iSight. Does that mean that the MacBook does have the capacity (chip) on the logicboard to do firewire, but apple decided to skimp out on offering the port? I've attached a pic of this said selection box in flash.
