Droid OS could act as smart HIFI OS enabling Youtube audio and other services which you can ask your smart HIFI or sound system to perform.
Also Droid could link into other smart appliances so you could be asking your HIFI to ask the Dish washer what maintenance it needs or you could ask your dishwasher directly.
rather than having one system you talk to to get things done All sorts of appliances could be droid network enabled.
so your sort of upgrading a lot of appliances to droids.
Droid is mainly audio and could one day replace the systems in many watches and even simple phones.
Not only could droid offer a connected mind for information and mainly audio applications. Droid could also one day enable thing like small smart phone badges like star trek.
Lets hope you can have a service via all means(mobile, wifi open zone and satellite) with one service that just does voice, text via voice and be able to ask it for information,
