The difference is that the quality of the 3G video calls was usually really crap, and most people thought that it cost a lot of money (well, in some cases it did). Just look at Skype, it's really popular, also with video calls. Video conferencing for business is also big enough that Cisco bought Tandberg for $3B. It just has to be good enough and easy enough to use that people won't have to think twice about it. The interesting thing here is that they are touting open standards (SIP, SRTP etc). If this gets traction outside of the Apple-sphere (which must be their intention), it might spell trouble for Skype as a proprietary, closed platform. If wifi calling "just works", then this, combined with Skype being demoed as a multitasking app, _might_ be a big "fuck you" to the telecom operators. Maybe I'm reading too much into it, but it'll be interesting to follow.
