For years we've been hearing about a refrigerator that orders milk for you when you're running low, but Google wants to expand the idea to the
entire home. Its Android @Home platform already has connected light bulbs, coffee pots, and more in the works. On top of that, Google has its
eye on moving beyond the home, to a much broader "Internet of Things." At the company's most recent developer conference, it rolled out its open accessory development kit for Android, inviting makers
everywhere to get busy connecting anything from small gadgets to big machines.
