Maxi. I guess you have used it and not just looked at someone else's review?
The siri voice is not like anything else on any phone. You just talk to it the way you always talk.
All I can say is what it is like for me and I have been using it for just a day.
It is great for sending emails and text messages, all you do is say send a text or email message to the persons name and then what you want it to say, it will then read it back to you and ask you if it is ok to send it. That is great for me as I have to send lots of emails and now I can do it when I am in the car.
It will also read a text message to me.
I have just got back from the fun fair with my family, before we left to go my wife asked me when does it get dark..all i did was pressed the button and siri told me the sun sets at 6:04, yes i could have gone on the web to find that out or even got an app to look it up but this was just done in an instant.
The new camera on the 4s is very nice. I know a thing or two about photography and i am very impressed. The video camera is also great with the new antivibration you can get some very professional looking videos.
