Separately, it's funny you should mention Skype and Facetime. The move with the Facetime 'open standard' seems aimed squarely at Skype, a shot across their bow, while Apple empowers them with iOS 4 multitasking support.
This is also interesting in the iPad. It had a mounting spot for a camera in the body, but shipped with it empty. Was the concession made to AT&T, who would offer a cheap data plan in exchange for refraining from giving the platform away to Skype? Was it simply that Apple needed more time to develop other plans in the VoIP voice/video space? Is it a form of coerced obsolescence? My guess is that Apple and AT&T (and other carrier partners) agreed to hold off on the camera until next year's 4G network model, as the wireless network could conceivably support widespread use of videoconferencing, making their offering much more competitive against Skype.
