For so long the iPhone has needed voice to text and the ability to perform actions with your voice. Siri is going to be amazing and with my job I travel quite a bit and frequently have a need to make meeting appointments, reply to messages and check the weather ... the only problem is I usually have to wait for a pit stop or traffic to stop to complete these tasks. If I had the iPhone 4S, I could complete these actions easily with my headset not having to delay or possibly forget about something. Hopefully I win because that would make my life so much easier.
