I totally agree that wearable computers like Google Glass aren't ready to replace conventional mobile devices. That's not what I'm saying. I'm saying that the webcam+screen model of video chat (not the keyboard+mouse model of computing) in the near future will be replaced by something like webcam+Rift+Omni. I think the technology will likely be mature enough within the next few years and that the public is already ready to adopt it. Before the 1964 World's Fair, the notion of video chat to accompany the telephone was considered science fiction. Even after the technology was demonstrated to the public, it stayed in the realm of science fiction, as seen in the film 2001, until the 21st century. I really think that being able to interact with other people in a digital world a la the Matrix would sell millions of units instantly.
