Martin Cooper, father of the cell phone, says 802.11 impractical for coverage: Sure, he's got a point, but the fellow is obviously opinionated and relying on a specific internal model of Wi-Fi hot spots that are monolithic.
One company "says they will have an 802.11b site within a five-minute walk in the city and a five-minute drive in the suburbs," Cooper said, bristling a bit. "Know what that sounds like to me? A telephone booth."
I can't make 11 Mbps connections to a DSL or T-1 line at a telephone booth, however.
I hear more and more about people driving up to closed (or open) shops and employing drive-by Wi-Fi: powering up the laptop, performing their tasks, and moving on. They'll have to enlarge parking lots next, not seating, at many cafes.
