I own one, have for over a year and I agree with Ginger. Most of what it does it pretty pointless. I use it for the same stuff as you do, like for music (but I would really like better speakers) and to control smart devices, but I have other devices that do both things better, since its easier to set up advanced stuff with other things (like iOS Homekit or my Sonos systems). Scores, sure, but I don't need them enough to make it a selling point, plus again, I have apps that do it better. I never just ask it questions, because 99% of the time my phone with a screen can do it better.
The Echo is neat, but I am not convinced it is anything special. I think one with a screen and stereo speakers would be a really neat kitchen device though, but really I think it needs better phone integration, which will only be possible with an Apple/Goggle device.
