So a few questions:
1. If all personal electronics are banned except for your phone then I guess Apple is screwed. There is no way to listen to an iPhone 7 without other electronics. (The headphone adapter is electronic. There's a DAC in there.)
2. I have a logic question. I know that in the case of security theater logic is not a factor, but I still must ask: if the concern is on flights going TO the US and not coming FROM the US then doesn't this mean that they feel that the TSA procedures in US airports are sufficient to prevent against this threat?
3. I wonder how soon this will apply to APAC, i.e. Tokyo? Soon, I would imagine.
