Echo connects to Alexa, a cloud-based voice service, to provide information, answer questions, play music, read the news, check sports scores or the weather, and more—instantly. All you have to do is ask. Echo begins working as soon as it detects the wake word. You can pick Alexa or Amazon as your wake word. [...]
It, "Alexa", arrives tomorrow. I wonder if it will be anything like HAL from the movie 2001: A Space Odyssey? That would be kinda cool, I guess. As long as she isn't the Beta version that murders you while you sleep.
UPDATE 12-08-15: So far, so good. It does everything they said it would. Only complaint, it can't attach to external speakers (but I knew that before I bought it.) It was very easy to set up, it's very easy to use. The voice recognition is really excellent. I can play radio stations from all over the world. When I want info about a song or music, I can ask Alexa, and she will tell me.
There are more features available if I sign up for Amazon Prime ($100 per year, which works out to $8.50 a month). I'm thinking about it.
