Off the top of my head from last night while cooking dinner:
* "hey google, add olive oil to the grocery list"
* "hey google, set a timer for 15 minutes for rice"
* "hey google, play some Christmas music"
* "hey google, how much time is left on the rice"
I could have fumbled with pulling out my iphone for all of these, but I would have had to stop prepping dinner, wash my hands, and then mess with the phone. Instead, it just fits in the flow of what I am doing.
