Getting started is very easy if you already have a Google Account. You log in and then connect the speaker to a Google launcher on your iPhone or Android phone. It only takes a few minutes. After that, the display begins to show information you think is valuable to you.
This includes the onscreen weather, how long it takes for you to commute to work, YouTube videos you may want, and information about flights that may have been recognized from your Gmail account. You can sweep over the large bright touch screen to see more information, or talk more commands.
I found it was very useful for cooking. I asked the smart screen for chicken cacciatore recipes and it brought up more than a dozen that I was able to sweep through. When I chose one, it showed me the ingredients in large, easy-to-read text. Then I went through the cooking steps one by one. After each step, I'll just say "OK, Google, next," and it would read me next step.
