I've been a fan of the Amazon Echo since it came out. Even at $180, it's a reasonable price to pay to experience the future. Amazon's virtual assistant, Alexa, keeps getting smarter and more powerful all the time. So when Amazon released its $90 miniature version, dubbed the Echo Dot, which does pretty much the same thing but has a less powerful speaker (you can connect to an external speaker via Bluetooth or 3.5 mm jack), that became a no-brainer. The result was it sold out and was selling on eBay for nearly $300!
