Considering the generous amount of foam packing material and box sizes of most Apple products, I doubt that was the reason. There's gotta be a CPU of some sort in the base to support the "computer-less" multimedia presentation capabilities of the PowerCD. Dollars to donuts, they were planning to grace the face of some FROG DESIGN packaged Mac with the "spinner" when 2x, 4x, & 8x data x-fer rated CD-ROM drives rendered such an installation obsolete.
IMHO, of course.
