I fully agree - let pax use those devices as long as it doesnīt disturb others, i.e. no talking to phones, no watching videos without headphones etc.
I guess itīs not about what AC wants, itīs more about some prehistoric government policies which were designed "just in case". IIRC AC did a pretty decent job at lobbying to relax the cell phone rules, so maybe weīll see some improvement over the next years...
