Echo isn't just for sound anymore. Amazon on Tuesday announced Echo Show, a new version of its popular smart speaker that comes with a 7-inch color touchscreen, 5-inch front-facing camera and dual 2-inch Dolby speakers. The unit is priced at $230 -- or two for $330 -- and will start shipping June 28. With its screen, it can show YouTube videos, access home security cameras, display photos and scroll lyrics as you listen to songs from streaming services like Amazon Music, Pandora, Spotify, TuneIn, iHeartRadio and others.
