The economics of wi-fi especially citizen wi-fi still intrigue me. People leverage lots of cheap pipes, optionally add some mesh technology and open it up with local wi-fi access.
Can you get “good enough” web access for free?
Will consumers pay the additional extra to get WiMax or Cellular data options?
As better applications for mobile data come out I think this will be significant. Just not sure if any particular model for mobile data access will win out.
Sadly it seems to me that the free wireless networks are all going to end up in the wrong places. Like meraki’s in San Franscisco. http://sf.meraki.net/
If you can afford to live in SF the cost of mobile internet is actually negligible. Go into poorer areas here or overseas and maybe the difference of a monthly payment has a bigger impact.
