I have three Echo Dots around the house now - my main use for them has been as voice-controlled Internet radios, which I find very handy, especially in the kitchen. The one on my desk in front of me now is hooked up to a desktop amp and decent Paradigm bookshelf speakers - sounds great. I also use it for (eg) Alexa, what's the weather tomorrow? Alexa, what's the news? Alexa, set a timer for 5 minutes. Alexa, play British Sea Power.
In one sense a Google Home would be preferable in that I could use it to play back my Google Music stash (1200+ albums). But it's not as easy to hook them up to speakers or an amp.
