At my old company we had MDTs similar to this:
It displayed essentially the same information that we received on our pagers (we were dispatched primarly by pager with pager and MDT giving us run number, pick up, destination, pickup time, chief complaint. Pager also had patient's name and room number) which made it easier to read than reaching down and getting the pager out. In addition it had the enroute/on scene/transporting/etc already programed in, which helped to cut down on a lot of radio transmissions.
