I admit that Siri has made things on the iPhone way more convenient, for example I can tell it to remind me of something 10 different ways it seems and it always nails it for me. Otherwise, I have to manually go through the steps, cumbersome at best. However, I still feel the need to go somewhere privately when in public or wait until I get home to talk to it without feeling stupid. I never see others talking to it either so I gather I'm not alone on this.
