Amazon today has unveiled Echo, a connected speaker that's always on, capable of providing information, music, news, weather, and more in response to your voice command. Think Siri (or Google Now or Cortana) packed into a cylindrical household speaker, one that houses seven microphones up top so that it can hear your voice even as it's playing music. 9 inches tall and containing a 2-inch tweeter and a 2.5-inch woofer, the device features Bluetooth connectivity, as well as accessibility through an app for Android and Fire OS (or web browser for iOS users). The Amazons Echo is priced at $199, or $99 for Prime members for a limited time, and can only be ordered through an invite from the company. Go here to lean more.
