What I liked about KITT was he talked to Michael without prompting sometimes.
Can we at some point get Siri to tell us stuff without asking, like telling me I forgot to take out the trash, I missed a call from so and so. Then I could say back yes I did take out trash and Siri would remove from list of to do.
I don't know about others, but I would like to be able to also name my personal assistant and give it a distinctive voice of my own. Why should everyone have the same name assistant and same voice.
They could even sell branded voices in the App Store or offer a way to change the bass, treble, etc.. Make an entirely new voice.
