In the future airlines will also conclude that you don’t have to turn off a reading device during takeoff and landing. On the way back from South Carolina I had to dash into an airport bookshop for a backup paperback, which sort of defeats the whole point.
But if the Kindle isn’t the future, exactly, it’s a precursor. What it tells you, even if you are an unreconstructed book lover, is that the future will not be as hard to get used to as you imagined. Books are heavy, the Kindle reminds you, and they take up a lot of room.
