Well, if we're comparing MOS 2.1 with AOS 4.1, then comparing Ambient with AOS 3.9's Workbench doesn't make sense. Workbench has been improved, although the basic way of accessing files hasn't changed.
Well... tmhgm was basicly pointing out how much Ambient has progressed in the last years. I have seen screenshots from new WB 4.1 listers but I doubt it still comes even close. Ambient is simply too far ahead right now.
But then I am an Ambient developer (albeit less these days) and also member of the MorphOS development team so it is not maybe fair to say so :-)
