Magid: Amazon's Echo brings to mind Star Trek and Hal

In a previous column I mentioned the Amazon Echo ($179 on Amazon.com) as a useful device for listening to music and podcasts. But, after using the Echo for the past month and hearing others talk about it at CES, I've come to the conclusion that it's far more than that. I bought the Echo as a music player because I was impressed at how easy it is to use your voice to play songs from your own music library that you've uploaded to Amazon Music along with the million or so songs on Amazon Prime Music, your Pandora playlists and the podcasts, music and online radio stations on TuneIn and iHeartRadio. You address the Echo as "Alexa," Amazon's persona that's equivalent to Siri or the OK Google voice commands for Android devices. Amazon also gives you the option to address Echo as "Amazon," but I prefer calling her Alexa.
