It's somewhat disorienting to read this, because it was increasingly wrong for such a long time and then in a strange way has bizarrely become almost right again in a limited sense. When connectivity and computers have become so ubiquitous, most people hardly find it necessary to lug a laptop onto the train to try to squeeze a few more minutes of keyboard-based work into their commute, and smartphones and tablets fill people's needs for general communication and entertainment so well. Even though travel is one situation where many people might find it necessary to bring a computer, it seems like laptop use on planes is way down, too.
