Who needs GPS when you have Wi-Fi?
The Loki service has mapped out the Wi-Fi networks in most major U.S. cities, letting you use your Wi-Fi equipped PDA, smart phone, or notebook to pinpoint your location. Loki installs as a toolbar in Internet Explorer or Firefox, which allows you to look up nearby movies, stores, restaurants, weather, traffic, and other information. My two favorite Loki services are driving directions and the location of Wi-Fi hotspots. Other channels provide Amtrak train schedules, a radio-station finder, apartment rentals, and real-estate values.
A nice touch: At the press of a button, you can send an e-mail or SMS with your location to a friend, who then clicks a link to look at a map and get directions to join you. Another way-cool feature lets you create “geotags” to attach to blog entries, Flickr uploads, and other Web-based content, showing the location at which it was created. Best of all, Loki is free!
