What are your thoughts on the mini? What exactly can you do with it, and does it work well?
I have one and it does almost everything a Google Home can do.
It doesn't sound as good as the speaker isn't of the same quality, but the microphones work just as well. You can say it to play it with supporting music services, control your smart home, use it as an alarm, ask it a question and use it as a personal assistant.....
My wife prefers the aesthetic of the mini to the home, so we're replacing a few home's with mini's and putting one in every room.
One nice feature if you're concerned about sound quality is that you can map it's sound output to a different chromecast connected device. So when I tell the mini in the bedroom to play a song from Google Play music, it plays the song on a different, higher quality speaker I have in the room by default. Once Google Assistant support comes to SONOS, this is going to be a fantastic feature.
One other difference is that you can no longer tap the top of the Google Mini to pause it or to bring up assistant without saying the hot word, but that's a feature I've never used with my Google Home and won't miss. I'm rarely right next to it as I speak to it from across the room.
For $50 it's a great deal. For free it's an absolute steal.
