This is part of the whole meta-data ideal – if your computer knows where you were at a given date and time, and the camera can tell the computer what date and time a photo was taken, then you can put the two together. Then, if that’s tied into your date book application, you link a location to an event, like “skiing holiday” or “Franks Wedding”, or (with a bit more intelligence) “After work on a summers day”.
I long for the day I can automatically record my life in that sort of detail.
