Regarding GPS Coordinates, I would like to be able to setup multiple preferred locations with a name like Aperture does.  I do not have GPS feature on my camera so that would be a time savior for locations I often shoot from.  Usually familly/kids pictures.  To beat Aperture ass, that would be really cool to associate some IPTC information to a preferred location so when we set the coordinates we can also apply location, city, state/province, country to the metadata!
