Jon,
Not sure if you had seen this article from 2014, but Gabe Perna wrote this one up about #ProjectedEHR.

Having the chromebook resting on a mobile computer desk typing on the keyboard navigating around the EHR is easier, when not worrying about tilting the screen just right so the patient can see also. I can move the wall mounted screen by tilting downward or side to side for best viewing to suite the patient.
