My biggest concern (apart from of course being kept awake by some tosser shouting into his phone about how good his glass of blubbly is at 3 in the morning) is the increase in air rage incidents that our cabin crew will have to deal with because of this stupid decision. As if our crew don't have to put up with enough shyte as it is, without much if any support from the company. They will be abused by the tossers when the system is not working properly (or when it's in "text only" mode), and will be abused by the passengers that the tossers keep awake with their inane calls and stupid ring tones. Stupid, stupid, stupid decision. I for one will be encouraging everybody I know to write this as a comment on the customer feedback forms.
