Primarily use mine as a speaker and HomeKit device. I have a couple light switches that I use with HomeKit and Siri works really well with control of that.

I also use it with Apple Music and from time to time as an AirPlay device. It also works really well for those purposes.

I don't typically use Siri for reading emails, text messages, or other things like that. I will ask it what the weather is as I walk out the door to determine whether I need to grab an umbrella or a hoodie or something. It also works well enough for that.
