The next air war will not be over Iraq. It will be over the Knee Defender which advertises itself as a way to “protect against reclining seatbacks on airplanes – save more legroom – can help you guard against economy class syndrome – thrombosis – DV”. It's a little piece of plastic that air passengers can slip on the seat in front of them, and freeze it in place — turning every seat potentially into one of those awful immobile ones sometimes found just in front of the exit row.
Already, one airline has banned it in response to traveler complaints. What drives people to carry a plastic block onto a plane to reduce the comfort of the folks in front of them? I'd wager that in most cases it is not a concern with proper posture, nor the supposed health advantages. Rather, it's to make room for that laptop—on which it so often seems the business traveler plays solitaire and watches movies…
Actually, this would make a decent law school exam question: does the deployment of Knee Defender in order to prevent the other passenger's seat's from reclining amount to the commission of any sort of tort? [I'll bet there are no contract claims against the airlines—they have their boilerplate down to an art form.]
