Incredible Tiny Device Finds Your Keys, Busts Car Thieves and Saves the Universe

It's no NeverWet, but as new products go, Tile has a wow factor that's helped it attract plenty of funding, if somewhat mixed reactions to its core concept. "It has never been easier to find your keys" is one of the product's big marketing lines—and indeed, Tile finds whatever you've lost, if you've stuck one of the little white Tile squares to it. Each Tile pairs with an iOS app, so when the item goes missing, you can use your Apple device to track it down.
