I think there is nothing wrong with the definition from Wikipedia. If you use a PC for scientific / technical workloads, it is a workstation to me. I don't think it matters if it has ECC Ram or it happens to be a Mac Mini. Gatekeeping the word "workstation" feels weird.

The NeXTstation didn't have ECC did it? And it was certainly a workstation.
