Now that nearly all "drawings" originate in some sort of CAD software, I would not accept this piece of equipment because of its overall size and that more than likely you and your students are going to see very little practical use for use a behemoth. I believe these huge digital tablets were originally used for converting hand drawings to digital and were a type of "tracing" tablet.
Just my two cents.
