Hi all So it turns out that the unibody iSight camera in my i7 17" is only 640x480 which is a dealbreaker for me as I need to do HD videoconferencing on the go. An external camera is not an option, neither is a Windows laptop. Has anybody had experience working on the unibody systems and the aluminium systems to know whether it would be possible to upgrade the camera in the unibody to what it should be? As far as I can tell, it's just a USB interface to the camera but I don't know how it looks inside. Thanks!
