Some Worries as San Francisco Goes Wireless - New York Times: "Users of the network in San Francisco will be able to choose from two options. From Google, at no cost, they will be able to connect to the Internet at the modest speed of 300 kilobits a second, about six times as fast as a dial-up connection but slower than cable service. The trade-off is that they will see a variety of on-screen advertising, though exactly what that will look like is part of the negotiations.
Or, for an estimated $20 a month, subscribers will be able to connect through EarthLink at roughly four times that speed and see no advertising at all.
