Spidere: Cell phones retrieves a mode of transportation and existence which would become nonproductive (due to being cut off from the rest of the world). Traveling by train becomes much more reasonable. The fact that planes are faster was a big selling point when every moment traveling was a moment away from the rest of the world...but when the cell phone brings the world to you, you don't need to worry about speed at the cost of comfort--you bring the world with you wherever you go. And so you can travel with access to the conveniences of comfort, without losing a thing.
