As Apple gets ready to ship its Pads with AT&T as the exclusive U.S. 3G carrier, the wireless giant's CEO seems to be downplaying expectations by saying the tablet computer will be "largely a Wi-Fi-driven product."

The basic iPad with Wi-Fi will sell for $499, and consumers who want 3G connections will have to shell out an extra $130 and pay AT&T $30 per month for unlimited data, or $15 a month for a 250MB plan. They'll also have to wait an extra month for 3G-capable tablets.
