Tony,
From what I heard about the test flights (and they were all tech or airline employees) the cell phones caused a yell-a-thon in flight, and one would think these were people trying to be civil and courteous. Even if technology catches up enough to bring the price down to what most carriers can afford, I don't see cell phones being allowed in the regular cabins. There has been talk of a "phone booth" type deal, but that is space most carriers would rather use for other purposes. Wifi would be great, if they can make it work at a reasonable price.
