In Japan, a wireless vision of future for U.S.

"Cell phones, or keitai in Japanese, are closing in on computers as the device of choice for surfing the Internet. While the Japanese are using their cell phones in the same way many Americans use their laptop computers or personal digital assistants, they also are pulling out their phones to watch TV, navigate labyrinthine city streets with built-in GPS systems, download music, take and transmit home movies, scan bar-coded information, get e-coupons for discounts on food and entertainment, pay bills, play Final Fantasy, even program karaoke machines."
