Slightly off-topic, but I'm actually disappointed by the spread of Internet access to things like planes and trains. One of the things I enjoy the most about flying is that I feel disconnected from the rest of the world, and I try to take advantage of this to focus on a book or programming problem for the duration of the flight, without worries or distractions. I haven't yet been on a flight with wifi, but I suspect that the illusion of isolation would be broken for me, and my ability to focus would suffer dramatically. Hopefully, most airlines will see it as another thing they can charge me for.
I am wholeheartedly in agreement with you, to the extent that I took a 36 hour train ride a few months ago partly to disconnect from the normal flow of life, and from the 24/7 Internet access that I am accustom to.
