David Pogue has reviewed the new multi-wireless HP iPaq H6315 in The New York Times.
"For distances up to 30 inches, the iPaq can beam information, like your electronic business card, to another palmtop using an infrared transmitter. For distances up to 30 feet, it has built-in Bluetooth circuitry (more on this in a moment). For distances up to 150 feet, it has a Wi-Fi antenna. And for transmissions around the entire planet, the iPaq has one other trick up its sleeve: it's also a cellphone. If your office can't reach you on this, then you must be on the International Space Station."
