I don't know what the first comment is all about, who wants an estimate, GPS should be accurate enough. The thing is although GPS is fab, in built up areas is is not as accurate as Wi-FI triangulation, thus I was excited when Kodak came out with its built in Wi-Fi card (okay, optional add on).
Of course the drawback with Wi-Fi being one has to be in a Wi-Fi area, might or might not have to pay for its use and its a battery drain, where as this is a seperate product but still requires a wireless link.
Still this is excellent news, I hate Sony but this will get the ball rolling surely. Someone create a Google Maps hack so its easy to upload the images
