Another leap: high-speed wireless connectivity. As data-transfer speeds of 400 Kbps become standard, high-quality streaming video will become a reality. The potential of Bluetooth, a wireless technology with a range of about 30 feet, will also bloom on the smart communicator, giving it the ability to connect to remote keyboards and displays. "You'll carry your whole life in your PDA," says Scott Summit, designer of the award-winning Tapwave Zodiac PDA. "And any device next to it--a computer, a TV--will reconfigure to run from it." Business travelers will be able to use it with screen-and-keyboard combos in hotel rooms and airports, where the device's expanded mode, complete with projected keyboard, might be awkward.
