I guess you didn't read what I wrote carefully because by P&S I was referring to the "kind of shots" that you can do with a 15-85+APS-C that you can't do with a prime.
If it's serious landscapes, portraits, action, etc. you can do all those with a fast prime just as good and most of the time better than with a zoom.
So the kinds of shots that you can get exclusively with a 15-85+APS-C will have:
* Overall shake (due to the reliance on IS, instead of taking a tripod and locking the mirror up)
* Little subject isolation (due to the slow aperture)
* Inaccurate focus because of less light going to the AF (so forget any real tracking but DOF is so big like on a P&S or a handycam, tracking is not even a real issue)
* Subject blur except in good light (again due to slow aperture)
* Bad bokeh (the simpler optics of primes in combination with larger apertures produce better bokeh)
* Heavy CA (due to all the extra glass etc.)
So, effectively, the shots that you can do only with a 15-85 IS that you can't do with a fast prime are P&S-like, lazy-tourist shots. So for that kind of thing I much rather carry a smaller P&S like my Nex-5.

This is by far the best example how a thread which started with somebody asking for help in choosing a lens becomes hijacked by some narrow minded individual with a religious belief in primes and no experince of the subject he is taliking about. If you have never used something you should really not be talking about it.
