Location data will be the next be thing in many lines of business. Marketing wise I keep believing it’s an underestimated opportunity. Look how easy it is already to track me, using Google Latitude and just my iPhone. I can show the world already where I went today.
It would have been really clever if Hotel New York had sent me a nice coupon because I was travelling towards the restaurant. Telecom operators already have this data available, personally I think it will be a matter of time before they start using this data on a more personal scale instead for just calculating traffic jams.
