I bit the privacy bullet and got an Echo for my home theater. It's nice, but there is a mountain of unrecognized value because of Amazon's desire to control everything. As a for instance, it would be nice if keyword enablement could mute the stereo. It'd be nice to Chromecast audio to it. It'd be nice if I could use it to play things on a fire stick. If it really wanted to be a device of the future, it would link to other Echoes in the house, allowed for intercom, and localized audio tracking. Some of these things will either come or never see the light of day because Amazon hates interacting with other companies (see: Android). I'm waiting for an open source alternative...
