Amazon's revamped Echo Dot is cheaper than ever and finally available to everyone

Amazon is making it easier to outfit your entire home with Alexa-enabled devices. The company announced a second-generation Echo Dot on Wednesday that costs just 50. The new Dot can be pre-ordered now--and by anyone, not just Prime members who already own the Fire TV or original Echo--but will not start shipping in the U.S. until October 20. Amazon says the new Dot, which essentially brings the Amazon Echo's voice controls to existing speakers and sound systems, has a new "sleek and compact design"--though the puck-shaped device was already pretty diminutive. The new Dot also comes in a new white option if black doesn't work in your home.
