The ease of use to configure different screens sizes and positions with just few clicks.The flexibility that allows us to change easily our content without any technical knowledge.The ability to add new features like live weather forecast and video players.The possibility to integrate all kind of applications and services such as social networks and Google maps. Nothing so far. I think it would have been better if we could have more options regarding the font size (we are currently using only Arial). We are solving the problem of displaying information about our clients' companies at their offices by installing several displays throughout them.
