Knee Defender: The dark side of product design...

I love the ability of good design to make life better for everyone. And then something like the Knee Defender comes along to remind me that it can be used for evil, too. It's a nefarious, wicked, irresponsible, and unfortunately effective device that prevents the airline passenger in front of you from reclining. It's been the cause of at least one flight-diverting in-air scuffle, has been banned by many airlines, and its accompanying etiquette guide is only good for a laugh. But hey, maybe it's good that this so-called "Me First" product has gotten some media attention - so that we all see how low we could go, and instead aim higher.
