Amazon Echo has just been revealed
Echo, easily one of Amazon's most ambitious products to date, is designed to make life easier for users, instantly playing music from your cloud library or telling you the local weather. You can quiz it with general questions and get answers from Wikipedia. Of course, Siri, Google Now, and Cortana can accomplish similar tasks on your smartphone — but Amazon seems to think there's a place in the living room for something like this. Amazon's assistant has a name too: Alexa. That's the phrase you'll use to wake up the always-on speaker. Echo won't run on batteries, which is another hint that Amazon wants this in your home all the time.
Some might say this is a massive invasion on peoples privacy, a HAL9000 in tube form or even a willingly bought NSA lostening device.. I'' let you be the judge. - I want one :o)
