We use them in our stores for digital signage - we use 60" screens in the store front and behind the food counters. We created web app that allows our Marketing team to allocate posters/menus/videos to stores or groups of stores. Changes are pulled by the store from the server every 60 seconds. If the store loses network connection it will just continue to cycle the existing images/videos until the connection is restored. Even with the price of the screens it's very cost effective compared to commercial offerings.
