Hehehe. Not trying to start conspiracy theories. Although I can be quite cynical at times (dont get me started on black boxes in automobiles) <img src="/images/graemlins/grin.gif" alt="" /> IIRC he was talking about some technology they were working on where you would have personalized mini billboard ads w/ audio on your cell in airports and on busses, subways, bathrooms etc based on information already collected through the current means (credit cards, discount cards, etc) and then the phone would tell where you are so the appropriate ads would be dispalyed in the appropriate places. Also talked about things like showing appropriate ads on the phone itself based on your location... ie: you walk in the Sears and the current sale items are displayed on the phone.
