I’ve checked emails, sent documents, and blogged wirelessly from cafes and from an airplane. The trend now seems toward super WiFi zones. The first time I heard about it was from the Minister of Education of Iceland a few years ago, who told me that Reykjavik would become a giant WiFi zone. Now it looks like Britain is on the way.
UPDATE: It turns out that the same move is underway in the U.S. The Washington Post (requires simple registration) reports, naturally, that the city will award a contract on the basis of free service to low income residents. (The rationales seem rather weak; access to WiFi is unlikely to be a big boost to getting out of poverty.)
