Vindigo is another company set to digitize the real world. They have sort of smart wireless yellow pages for the major US cities, with walking directions and other practical information on places to eat, shop and play.
I predict interconnecting meatspace with the net to be the next big thing. I’m only 16 years late after Neuromancer (hint: I’m cross-selling my other site here.)
