Interestingly (or maybe not) there's a coworker of a coworker where I work who actually worked with RPF and said the same thing.

I'm not sure which books you mean, though, his pseudo-autobiographical books or the ones like "Six Easy Pieces?" I can understand dislike of his conceit that comes through in the former, but the latter books are brilliant. He has a method of cutting right to the important stuff with just the right amount of supporting detail.

Examples:
1) his discussion of symmetry in SEP
2) his explanation of energy and entropy in FLOP (I gotta believe the acronym is intentional) is extremely clear and has been borrowed by others to make the points.
