One of the most important qualities of a laptop is battery life. If you can make your laptop last 10% longer than the competition's, it will sell better. Consumer magazines rate laptops according to how long they run on a charge. And the holy grail of laptop computers is to be able to run LAX-JFK on one battery. If a laptop computer loses energy to electromagnetic radiation, that energy is not available to power the computer. For this reason, the companies that design laptops spend extraordinary amounts of time and money testing and reducing the RF radiation from the computers, not because some government agency makes them, not because it will be kinder to airplanes, but because it will be more profitable. For this reason I am quite certain that laptop computers do not bother navigation equipment. I have no knowledge of cell phones, but their purpose is to transmit RF signals, so this economic argument would not apply.
