All of the above says there could be any number of reasons his projected slides were not super sharp, even if the macro was.

Sometimes the lens defects in the slide projector's lens can make a good slide (taken with a good camera lens) look bad. So, do you know for sure that the slide image itself is soft at the edges? (Have you checked the slide with a loupe?)
You may be right, this could be due to projector. I do not see this behavoir when viewing on the 17" monitor.
I have been right only on very rare occasions, Ramesh, so don't take anything I say too seriously - <g>.
In this instance, I would say you are right. Slide projectors tend to have really bad lenses, though I am sure there are exceptions. Also, there is no guarantee that the slide is perfectly parallel to the screen, or that the curvature of the lens field is identical to the curvature of the slide (there will be some, unless it is glass mounted). As well, to get maximum light transmission, projector lenses tend to be pretty fast optics, which leads to a whole nother set of problems. Making a decision about camera lens quality by viewing a slide show isn't thinking things through very well.
