On the Microsoft Virtual Academy web site, http://msdn.microsoft.com/dn338454 , if you look at the image for C# basics (and others); what are the 'screens' they are sitting in front of?
Well, going by the picture of the guy in the lower left corner, in the puple shirt, the device might well be made by PLANAR.
And a quick google for "large touch screen planar" finds the Planar Helium PCT2785 touchscreen monitor -- "An edge-lit monitor that's probably only worthwhile for corporate users."
