Amazon Echo Show 15 review: A big device for a small audience

Amazon's Echo Show line has been around for four years, but until now the screen sizes have ranged from five to 10 inches, making it ideal as a multipurpose bedside alarm or a companion screen in the kitchen. The 15-inch Echo Show 15, available now, is by far the largest size Amazon has attempted, and it's also notably the first Echo Show you can mount on your wall. Because of that, the company is betting some people will use it not just as a digital photo frame, but also as a family bulletin board. If that's specifically what you want out of a smart display, the Echo Show 15 could be a niche but very fitting match. Somehow, though, we suspect that's not most people.
