Google Home review: In catch-up to Echo, but with promise

USA TODAY'S Ed Baig compares Google Home to the Amazon Echo. Ask Google Assistant inside Google Home what it thinks of Amazon Echo's Alexa and you get a gracious reply: "I like Alexa's blue lights. Her voice is nice too." Civility aside, the standalone $129 Home speaker that becomes available Friday is Google's answer to the $179.99 Echo speaker, and a potentially strong answer at that, though Google is still in catchup mode and too often answered my voice queries with a "sorry I don't know how to help with that yet."
