Bill,
My concern is mainly cell phones, but also anything else that transmits; I saw a boy try to use a radio control car in the aisle not too long ago. If you'll reread the last paragraph in my earlier post (reply #35), you'll see that I'd support a partial lifting of the ban now.
Also, you're probably correct in that airlines would find a way to impose a fee for phone use. They're earning billions in bag fees already.
Blue skies,
