Amazon's Fourth-Gen Echo Looks--and Sounds--Even Better

It's been a few years since Alexa first started listening to me everywhere. After an initial honeymoon with an original Echo Dot (a device I still maintain is the best alarm clock ever), I've slowly filled my house with Amazon's review units. These days, I mostly break out Google- and Apple-made speakers for comparison testing. The fact is, Amazon's smart speakers work so well, there has never been a reason to switch my whole system. In terms of price, compatibility, audio quality--and now, thanks to a sleek, round redesign, looks--the new Echo remains one of the best smart speakers for most people.
