iPhone: set time based reminders, set location based reminders, add items to grocery or other shopping lists

AppleTV: fast forward or rewind (fast forward 2 minutes), rewind + temporarily turn on closed captions if I can’t understand what someone said (what did he say?)

HomePod: turn on/off lights throughout the house, set time based reminders, set location based reminders, add items to grocery or other shopping lists, check outside temperature, ask if it’s going to rain, turn TV on/off, play music, unit conversions while I’m cooking (how many tablespoons in a cup?), ask what time a store opens/closes, ask when was the last time I did something (it checks your calendar)
