i agree we shouldn't even BEGIN to speculate with these threads, but a point I wanted to touch...if I may...a bit of reality perhaps...but what is the point of even bothering with mobile video conferencing.
My argument against video conferencing is that it isn't really practical. A mobile device like the iphone is built for mobility and on the go usage.
Things like video conferencing requires you staying put...are you really going to be THAT douchebag walking down the street video conferencing in public...one would assume video conferencing should be taken in a private setting where you can hear each other(do u really wanna be talking to your phone with your headset on? I don't get the real world practical on the go use for video conferencing. Even if the iPhone had the ability I wouldn't even use it which leads me to believe that apple left it out for a real good reason. If i wanted to video chat i have my desktop and laptop for that, and hell I don't even have the need to do that. If it was a business thing well then you have systems at work already set up for that...
