GPS feature in Google maps

wow.. this is a neat feature. I hope "My Location" gets tuned up well to be more accurate. One of the reasons I didnt want to go with iPhone was that it lacked a GPS. Technologies and applications like "My Location" could sure bring smiles to all those people who lack GPS enabled phones. btw, Google specifically mentions that it doesnt track any person but just locates a mobile phone through the cell phone towers.
