Amazon's latest Echo speaker has an all-new spherical design

Last year's Echo was a complete home run for Amazon -- it delivered excellent sound quality and responsive microphones for a relatively inexpensive $100. So how can it make the flagship Alexa speaker any better? It's still $100, but now it looks even more like something ripped from a sci-fi film. The flagship Echo is also being joined by a new Echo Dot that also looks like a sphere, and keeps the low $50 price. There's also an Echo Dot with a clock display for $60, which could make a great bedside companion.
