I'm trying to figure out the definition of "cabinet saw". How does it differ from a hybrid saw. I pretty much understand the "contractor saw" designation.

For example Grizzly G0771Z has a full length cabinet with the trunnion mounted to the cabinet but its considered a hybrid saw. It was my understanding from previous forays into woodworking that a cabinet mounted trunnion was what made a saw a cabinet saw.

Is it the weight? All cast iron top? Motor type and how its mounted?

Can someone explain the differences.
