Keith is a fan of the Amazon Echo because he is vision impaired. Leo says that the Echo is great for accessibility because he can talk to it and get the necessary replies. It's not perfect, though, of course. It doesn't make phone calls yet. Right now, he could "drop in" and make phones calls to other Echo users. Some day someone may make a skill for that, but Google Home, by contrast, will be able to make a call to any phone number via Google Voice. So for that option, Google Home is the better option.
