Amazon Echo Dot (3rd gen) review: A big step up in terms of design and musicality

I called the second-generation Echo Dot "the Echo most people should buy." If you already have one, the only reason to upgrade to the new model is for its superior sound. The third-generation Dot is also prettier. It still looks like a hockey puck, but it now has softer edges and it's wrapped in your choice of charcoal, sandstone, or gray fabric. But if you're buying a smart speaker for all the things it can do besides playing music, the second-gen Dot is still around (though who knows for how long), and it costs $10 less.
