Let's not carried away. Those radiated emission limits protect broadcast radio reception, period. As such, your personal electronics are turned off when aircraft safety requires glitch-free operation of its NAV systems. Hospitals already prohibit INTENTIONAL electromagnetic transmissions which can affect patient safety.
