Answer 2: Enamel is the hard material that coats your teeth, and is made mostly of a mineral. However, we call other things enamel. There's enamel paint, which is totally different, and there's also porcelain enamel, which is used to make a lot of dishes.
All of this is due to Amazon's unique approach with the Echo. It's not a portable speaker like we've seen from Jambox and Logitech. Instead, it's a rather large, cylindrical device that needs to be plugged into power. It's something you'll likely just leave in a single spot in your home.
Compared side-by-side with the Echo, the Dot is just as responsive to voice commands: itâs able to hear my voice from across the room, while playing music, or while my two kids are running through the house raising hell. The Dot does have a small built-in speaker, which works great for Alexaâs voice replies and confirmations. It can be used in a pinch to play music, but it certainly isnât room-filling or particularly good sounding. Thatâs where the Dotâs new ability to hook up to a larger speaker comes into play.
