What's the practical difference between a mobile pedestal and one that's built into the desk?

A fixed pedestal is structurally part of the desk — attached to the frame with no wheels, not removable without disassembling the workstation. A mobile pedestal is completely freestanding on casters and moves independently. Mobile units are better for reconfigurable offices where layouts change; fixed pedestals give a cleaner built-in look and slightly more stability. Many commercial desks offer both as options.
