Question: what is the difference between the echo dot and the echo 2nd generation?
Answer: Basically, the only difference between the two devices, other than size and cost, is sound. If you're just looking to be introduced to Alexa, you'll be fine with the Echo Dot. It has all the smarts of Alexa in a small speaker. ... Now, whether you want to go with the Echo Dot or Dot with Clock, that's entirely up to you.
