I see a market here !!! Streaming porn ! Pay per minute, no nasty tell tale files in your temp directory for your wife to find.
I can imagine the following:"Honey,I want a 6680"..."But love, none of your friends have 3G phones".
But seriously now. The video feature will have a serious impact on the service industry. Just thinking about my access control systems. I have recently resigned from my company, but every so often a system goes poof and I have to be contracted to drive out to the site (generally the one 200km away). I can invoice R400/h and travel, but I have found that I generally lose out on time and flexibility. By having video a service a techy can drive out to the site and physically show me what the system is doing. We had a case like that last Friday. The client just called to say that nothing is working. My ex-partner had to drive all the way with a spare system and a boot full of tools. With a video phone he could have sent a low paid techy to show me the lights and I could have told him to just flip a switch that some idiot turned off. Even at R2/meg that service would have been a lot cheaper than having someone of management driving all the way out.
But then you might save on bandwidth on the long run by using a laptop and webcam, along with MSN. I have had some good video chats even on GPRS. Long delays, but you get the general idea where that person is, what he is doing (and who he is doing it with).
I think with video you will have less of a chance to see the other person. A lot of people are very self consious. Many have to mentally prepare themselves to even make a voice call. Men should be easy, but my wife will have to dress and do her hair and face before making or receiving a video call.
Calling in sick might also be a problem

Your boss might want to see your face and the backdrop scene might just resemble a shopping mall and not you bed's head rest.
I think for the lower end market it will be a novelty. For the higher end it will definitely be an added bonus. But, as I said before, then you can just as well buy a cheap laptop, webcam and a 3G contract and work via MSN. The nice thing about the laptop is that you will be able to have all you required software and be able to exchange so much more.
Only time will tell.
