Okay, quick post because this is too awesome to not to write about it. Rafael Rivera from withinwindows.com and Long Zheng from istartedsomething.com have put together a driver for Windows Location API in Windows 7. The driver provides geolocation information for location-aware Windows applications using Google’s Location Services. All it needs is your WiFi turned on (or your IP address, but that’s less precise) and internet connection.
I am really impressed by the accuracy of thins thing (2 locations tested so far and the accuracy was ~30 meters). The best thing: it’s free. Go grab it from geosenseforwindows.com.
