Getting started is really easy if you already have a Google Account. You log in and connect the speaker to your iPhone or Android phone through a Google Home app. It only takes a few minutes. After that, the display will show information that may be valuable to you.
These include the weather on the home screen, how long it might take for you to commute to work, YouTube videos you might like, and other information flights it may have detected from your Gmail account. You can swipe over the large, bright touchscreen to see more information or to speak more commands.
I found that it was really useful for cooking. I asked the smart ad for chicken cacciatore recipes and it came up with more than a dozen I could wipe out. When I selected one, it showed me the ingredients in a large, easily readable text. Then he led me step by step through the cooking steps. After each step I would simply say "OK, Google, next" and it would read me the next step.
