this could be magnificent....if done right
imagine coming home, its dark, you press the button on your watch "turn the lights on siri"

tada
then maybe "i want to listen to "insert song name here" and it would start playing on airplay from your mac, through the apple tv, mac speakers, and hifi connected to an airport express
there are loads of possibilities, aslong as siri is upgraded along with it
"siri, has 'insert name here' emailed me back yet?"
at which point, siri can say yes, or no, and even read the email out, you can dictate one back
"siri, have i had any more texts from 'whoever'"
siri will tell you and read them out, you can dictate answers...
there are loads of possibilities if done right
could even do "siri, i will be home in 15 minutes, turn the heating on"
and if you have an app controled boiler, and a 3g enabled watch (or bluetooth and 3g through iphone) it will do it
this is heading in a star trek direction now....excelent!
