Siri's a joke and a desperate attempt of a high tech feature that screams, "look at me, I'm cutting edge!"
Or it's a beta product that has the potential for app integration and can turn into a great feature over time.
Also, realize that Steve Jobs was still alive when the iPhone 4s was announced and knew that Siri was going to be incorporated into iOS 5
Siri is just a Google-y kind of feature that only impresses people who have a brain similar to that of a hamster's.
Nobody needs it.
A few points that I'm too lazy to make into paragraphs:
1. Jobs died the day after Siri and the 4S were unveiled. I'm pretty sure he knew what was going on.
2. Siri isn't actually bad, it just isn't as great as Apple make it out to be. It should not be a key selling point IMO.
3. It's unusual for Apple to launch a beta product, that is why people are not used to it having problems like it does.
Apple would not have released a beta product to the general public in the past.
