Luggage Robot Follows You With Your Stuff
Take a look at the picture. I know what you're thinking, because I thought the same thing when I first saw it. "What the f*** is that?" To my disappointment it turns out to not be a big blue train coming at you, but a luggage robot. A Russian based company will be selling "Tony", the suitcase that follows you, starting in 2009. You carry a card in your pocket and the little bastard follows you around the airport using its robotic brain, internal gyroscope, and all kinds of other detectors and sensors. If someone takes it or your card an alarm goes off. The company is already taking orders, and will gladly take your $2,000, but I'd wait if I was you. I typically don't advise buying an item in advance that only exists as an incredibly shitty drawing in Microsoft Paint.
Note: Yes, that's the real picture they provide.
