They need to do better with the language recognition in these things. As soon as I have to stop and repeat myself it's already become irritating. I'd rather just type and search.
Otherwise, I'd love to be able to talk to the house computer and have it understand me. "Computer, I'm in the mood for a new turn-based strategy game, maybe something with a sci-fi setting. What seems to be good that's come out over the last year?" I want to be able to talk to it like that, just as if I started a thread with that question on Qt3.
Also, about the music, it says this: "Listen to your Amazon Music Library, Prime Music, TuneIn, and iHeartRadio." What about Pandora, Spotify, iTunes, etc.? Shouldn't I be able to say, "Alexa, put on my Pandora blues station." I also want, just to be puckish, to tell it to search Target.com for good online deals.
