... a friend was visiting some eastern European country where the alphabet is strange and the pronunciation even stranger, and he couldn't pronounce the name of the street his hotel was on. So when he needed a taxi to take him back to his hotel, he showed the taxi driver the name of the street.
With a digicam, you can take a picture of your hotel and the nearest street sign, as well as any nearby landmarks, and then show those pictures to your taxi driver or to anyone you might need to get directions from, and this would be even better than just having the address on a piece of paper.
