So what I'm hearing is that if I had P4 already sans PP, and got P5 with SR2 thinking it would cover the functionality of PP, it would still be worthwhile to get PP for my P4, if the non-overlap is of sufficiant interest? The two versions are different enough, and have enough complementary strengths and weaknesses, that I have found myself using both, depending on the task at hand. Ridiculous, but not out of place in a world designed by a mind that gets off on frilled lizards and televangelists...
