Google has just announced that accessories will be available for their android@home system by the end of the year.
The idea is to be able to control the devices in your home from your Android smartphone.
Lighting, dishwashers, heater timers and so on can be controlled and monitored from wherever you happen to be.
Not only can you will you be able to unify all your remote controls into one device, you will also, with the addition of RFID embedding in household items, be able to detect what things are where in your house. Possibly making a search for the car keys a thing of the past.
