The total cost of using Windows is (probably) lower than using Linux. These displays are often custom work - building something like that is a couple of days work for a WPF or Flash (/Air) developer. The vast majority of those use Windows. And I've not even touched on the administration costs.. To be honest I'm more concerned when I see ATMs running Windows 98; at least these advertising displays can't do any real damage...
