Workstation is not an advertising term. Before the first workstations appeared, people had to buy a sequencer and fx units separately. Then Korg, Ensoniq and others started slapping on the sequencer and give the sounds some basic digital fx. I know because I used to own one of the first generation (digital) workstations, the Ensoniq SQ1+.

The term workstation doesn't have anything to do with realistic instruments or the fact that samples are being used. Same goes for synths. There are synthesisers with built-in fx, that can't be called workstations.

Btw, bvan, memory isn't measured in milligrams.
