For me It's Cortana I use most. I pick up the phone hit the button and ask what's the temp outside. She then tells me and shows me a graphic with the forecast. If I am looking for something near by I ask her. Is there a Krystal nearby? She then shows me there isn't but the closest one is like in another state.
I miss those little sandwiches. I also ask her to remind me or set an alarm. I guess you can say she is my PA and sometimes she gets sassy ask her to tell you a joke. They are pretty bad. lol
