One of the big themes of CES this year is Android everywhere. There are Android phones, there are Android netbooks, and there are Android ebook readers. It's even bigger than that. I spoke to Touch Revolution. They make and design products that other companies use under their own brand name, and this year they came out with the NIM1000, a touch interface that can be customized and used for a variety of devices.
Among their demo prototypes? A microwave and a washing machine. That's right, your washing machine might be Twittering to your microwave while you're not looking. Devices like that would generally use some interface elements from Android and not the full feature set. It wouldn't make much sense to have your microwave download a Facebook app, but it might make sense to have a microwave that can download recipes or a fridge that you can use to order more milk.
You will see Android powered medical devices (though he wouldn't tell me which ones) and Android will power the interface on the back of chairs on airplanes at some point in the future. The future really is being taken over by Androids!
