Do people find Sri and Google Now actually useful? I hardly ever find a use case for it, even when I am driving. I just think people should disable Sri and Google Now by default, and only activate after pressing a button.
Yes, I personally find Siri very useful. I almost always interact with Siri through my watch and I do things like start a cooking timer while my hands are covered in raw chicken juice, set a reminder to do something tomorrow, or reply to a text via voice while driving.
