This kind of thing blows me away. Powerful, flexible telepresence will transform the way we work, go to school, and go on vacation. Our kids will interact with the world more virtually than we have... they'll probably be jealous of all the travel we do now, but they'll have different vistas open to them than.
Imagine being able to rent-a-robot at your favorite vacation destination for 1% the cost of going there yourself? Sure, an iPad interface is primitive, but the controls will become more immersive over time.
