Other Web-connected devices such as Apple's (AAPL) iPhone and Microsoft's (MSFT) Xbox gaming console have begun powering applications by using Facebook Connect, letting friends play games and catch up with each other, even while they're away from the PC. This is just the tip of the iceberg, says Facebook's Cox. With a greater variety of devices connecting to the Internet, from TVs to GPS units in the car, Facebook sees potential to work with manufacturers on designing experiences oriented around people, instead of information. "If you as a user could expose your information in a way you are comfortable with, and that was safe, you would have much better experiences with these devices," Cox says. Think of getting in your car and telling the GPS to give you directions to a person, rather than a specific address.
