The author notes some interesting discrepancies, particularly IE9 incorrectly identifying the city. IE8, as expected, lacked support, and Safari for Windows also showed unexpected behavior. Further testing on a Mac is planned. A code sample demonstrating HTML5 geolocation with Google Maps is provided below. The author also points out that geolocation has applications beyond map plotting, referencing W3C use cases for further examples.

Code Sample:
