I agree with the comments regarding definitions and trying to figure out what technologies will be in widespread distribution by 2009. Robots, however you might define them, might exist by 2009, but will there be widespread adoption by 2009? I doubt it. Remember, whenever we choose a technology, a criterion of that selection inevitably includes “Does everyone already own one? or Can we afford to buy one for everyone?”
I agree the big miss on the list is cellphones and PDA’s. They are already widely adopted, 802.11n will be in place in a few months so vendors will have a myriad of inexpensive tools for the standard by 2009, and we will have had a chance to experiment with their best use by then. That’s where I’d be putting my money if I could.
