Was the 12-Inch PowerBook G4 truly the smallest Apple notebook at the time of its release?
Sort of. Apple stated that the PowerBook G4/867 12″ (Al) was its “smallest notebook ever”, which as some have noted, is true if one measures the volume of the notebook, but compared to the long-discontinued PowerBook Duo 210, the 12″ PowerBook G4 is thinner (by 0.22 inches), but it is slightly deeper (by 0.1 inch) and heavier (by 0.4 pounds). All 12-Inch PowerBook G4 systems use the same case.
