The utility of this is somewhat moderated by limited geographical mobility while a phone's active in a single session. One rarely drives from San Francisco to LA typing all the way on their smartphone data connection, for example.
That's true to a limited extent today. It's not likely to remain true. (No, it won't be the driver typing on their smartphone data connection, but it will be the busload or high-speed trainload of people typing, gaming, etc. all the way from SF to LA and/or other non-interactive data usages that are becoming more and more prevalent. Further, the speed of handoffs will have to get faster and the address stability area larger as that starts to include things like airplanes. Owen
