Siri uses discussion

Siri has been marketed as an integral feature on the iphone 4s. In commercials, people talk to Siri when running, driving, or as part of their daily life. Do people find it useful?

From my own experience, Siri is a convenient way to set my alarm at night. It is a fun toy for my kids to play with. And that is about it.

How do you use Siri? Do you set reminders, appointments, send texts, or other things?

As an aside, I find it frustrating to use in the car. When attached to Bluetooth, Siri is hijacked by my car stereo which leads to delays or just overall failure. I wish Siri couldbe set to work locally always and not in Bluetooth (yeah, i know I should be handsfree)
