For whatever reason, I'm a little fearful of flying, so wifi will be a more than welcome distraction/time waster. On the other, I do see the point about losing the one last place where you're truly free out of contact. I see this change as being inevitable though. We corporate types will adapt, just like when the blackberry came along and took away our nights and weekends.
For those of who are self-employed and cannot "get away from the boss's expectations" anyway... I would really appreciate the opportunity to be productive on a cross-country flight.
As for those expectations of being at beck-and-call 24/7... corporate bosses (and clients) need to have some limits set. And that's not an issue of technology - or one to be solved by reduced technology.
