This entire argument is just stupidity. Nobody disputes that there have ALREADY been tens of thousands of these electronic devices left on in the past year with no noticeable interference. No expert (and your friend that heard someone say they saw some interference once doesn't count) seriously believes there is any way these could cause significant interference.

But the government has to mandate the most expensive testing program known to man because nobody in a position of decision making is allowed to consider any reasons why an iPad might be different than a raygun or a Van de Graaff generator or a live tiger.
