The Holy Grail for geotagging for me of course will be when Canon actually includes GPS in a professional grade digital SLR built in – or at a minimum offers an external battery grip type GPS device that can be added to a Canon digital SLR to add geotags based on GPS.
Bottom line is though that we are only seeing the beginning of geotagging photos. I think it’s only a matter of time until every digital camera produced includes geotagging capabilities.
