Re: So how is the camera?
 

I tried this feature, but I don't know how to take advantage of this. I guess the GPS coordinates are added in the picture, but I have no applications that use those coordinates.

Is there a way to link those GPS picture with google maps or any GPS/map applications ?

If you upload the picture to a site like Flickr, it should show up on the map. Lightroom will also happily show the image on a Google Map, if it is properly geotagged.
