The only thing which is needed but still not achieved across the industry is reliable and fast internet and email access inflight from pax own laptop computer and inflight phone/fax.
The first time an airline has a cheap inflight phone system, is the last time I will fly with them.
It's bad enough on public trains, with people giving the rest of the pax the benefit of the conversation. Can you imagine the numerous cases of "air-rage" this will cause when some people are trying to sleep, and othere are constantly jabbering on the telephone.
