Second, Wi-Fi "phone" calls aren't being allowed (so far). These are technically called "Voice over Internet" phone calls, and typically require a headset and free software (like Skype). So far, these are not allowed -- and more and more folks are asking, why not?
Finally, there's the, uh ... porn ... issue.
Flight attendants have gone on record as saying it should be banned from all laptops, but there's no law against it at the moment. I suppose fliers can and do flip through racy Web sites and use their various devices to view movies their mothers wouldn't approve of, although frankly, I haven't noticed this. I do think if everyone just calms down and uses common sense, this will never really be much of an issue. Of course if it is, we can always send these folks to a separate seating area -- that's right, a "special" area just for porn perusers.
Not so long ago, I saw a comment from a cell phone company executive, who was not happy about efforts to stop cell and Internet use on our airlines. He was getting a bit worked up and finally asked what were they going to ban next, alcohol? Well, nothing's impossible (wonder if he's forgotten about that little interlude known as "Prohibition," or that on some planes, your Scotch is going to cost you $8 a pop), but I think the time is ripe for cells to join Wi-Fi, and most of us will be fine with paying for these "must-haves" of the modern world.
Now, if you'll excuse, me, I just want to make sure I haven't misplaced my noise-cancelling headphones.
