“sending message”, “message sent” bla bla SHUT UP WOMAN
There is a setting so she/he won’t keep answering back.
I have the 4S and use Siri quite a lot. I use it for appointments in the calender, reminders, lists for shopping, bike list and things. Also great for googling, conversions, it really does feel like a personal assistant on the end of the phone.
Having JB 4S also helps, as it can now translate, open apps, change settings (wifi on/off, brightness, etc), post to twitter/facebook and a few other things.
I think its pretty damn good with it hooked up to the car stereo, hands free assistant.
I wouldn’t upgrade just for Siri though, but now I’m using it, I sure as hell couldn’t do without it, it would be a right PITA if it was gone.
