Did you figure out more fun you can have with DOT?
I'm still learning. There are some fun questions you can ask, especially if you are a fan of sci-fi-ish pop culture references. (Try a couple of classic Star Trek commands.) Mostly I have used it to listen to music or sleep sounds. I've also asked the temp outside, for news headlines, and for weight conversions when I was making cat food. One cool thing is access to all music on Amazon, it's $3.99/month, definitely worth it. I haven't used it to ask my phone to call people, and probably won't. I don't talk on the phone that much. You can ask her to play a game, and there are several, but I have just now started exploring them.
J liked hers so much that she ordered the full-sized Echo, which has amazingly good sound quality for such a small device, to put in the living room. Then she got a speaker to fit upgrade the dot in her bedroom, decided it isn't as good as the full-sized model, ordered another full-size to replace it, and is giving me the speaker for mine. We also got one for the screened porch, just a dot, and mostly to use as an intercom, although I will probably listen to music on it, too. I spend a lot of time out there when the weather is nice.
