There was a recent article in the New York Times written by John Markoff entitled "Global Dreams for a Wireless Web" featuring Fon and its founder Martin Varsavsky. I would comment on it, but I think I will skip that for now. Some linkage for your reading pleasure:
Martin's Blog: "John Markoff´s great article on Fon"
Fon Blog: "FON Featured in the New York Times"
New York Times: "Global Dreams for a Wireless Web"
EDIT: It seems El Fon Blog decided to comment on the article
