It is starting. The first airline, Emirates, will be allowing cell phone calls on planes. And the FAA is considering allowing it in the US. I have no problem with people using PDAs in flight (assuming there is no safety issue). Heck, I don't really have a problem with PDA in flight unless it involves the couple sitting next to me and they start entering my personal space. But I like being able to relax on a flight, do some work, or, as is my usual wont, get in some good reading. Now if everyone can jabber while on board . . . . Well, it will be a nightmare.
