On the surface, you would think that the huge cost savings are the main benefit to an instructor.  However, that’s not the case.  In a typical computer lab, a great deal of effort is expended at in “ghosting” the computers, or preparing them with the appropriate software for the lab. 

Thin clients save a great deal of time, labor, and frustration because the software only has to be loaded once, on the server.  For example, if you have a lab with 20 machines in it, and you need to load a new version of MS Office, you would either load it on 1 machine and copy that image to the other 19, or load the software 20 separate times.  With thin clients, you only have to load it once, taking only 1/20th the amount of time it would normally take to prepare a lab for instruction.  This will allow an instruction to change software and lab configurations much more easily.
