Say you didn't care about making it better or unique in any way, and just decided "we're going to make 5 new board layouts using the exact same tech as the 60HE, but in a different shape and format"
How much work does that take? Is it as simple as dragging some icons around and clicking "send to board printer", or does it take months workshopping the design with your entire team? What sorts of challenges do you face that aren't obvious on the face of it?
