News: Nokia connects laptops, cell phones
Nokia on Monday will unveil a modem for laptops that can access both
802.11b networks, which laptops use to surf the Net wirelessly, and
cell phone networks.

The credit card-size device would let laptop users roam from an
802.11b network to a cellular network without having to shut down
their computers, insert a new modem, and then adjust the settings.
It also helps save on costs of buying two different wireless modems.
