Here´s an article on BW with a great commentary on the part of Michael Dell supporting Fon. Fon has already grown quite a bit in the States but in this large country we are still far behind the UK and other smaller nations in spreading Fon. My view is that Fon is a standard for connecting to WiFi and as GSM has shown USA tends to come late to standards that are not home grown, but they tend to adopt them in the end. I am confident that Fon will eventually make it big in the States as well. Especially as we move into .n foneras, wimax foneras, femto foneras which are necessary in many parts of the States in which people leave farther away from each other.
