The rich get richer. Silicon Valley is being blanketed by Wifi provided by IBM and Cisco. Communication costs are about to zero out in the Valley. Always on for every device is now real. The advantages to doing business in the Valley continue to mount rapidly with this announcement. The idea is important. Its always the Valley that keeps making the one more step forward that keeps it at the front of rivals worldwide.
When change as big as today's is sweeping through, the biggest losers are the people who believe that they are already doing well. Valley WiFi shows why doing well today isn't a valid argument. You have to keep moving to the edge as fast as possible.
Could wifi be a transitory technology? Sure. But in the meantime it will have served its connectivity, business and leadership purpose in the Valley, if no where else. And then it'll be time for something else.
