I think it depends on what sort of photography you do. I have a Nikon DSLR with several lenses, and still keep a PaS in the bag for when I don't want to carry the whole thing - usually when I'm biking or some such where I'm doing more casual landscapes. (I readily admit I suck at landscapes - don't know if it's my camera or my color-blind eye, but I'm guessing eye.)

But the PaS just can't take candid portraits like my 80-200 f2.8 zoom on my DSLR. Yes, it's big. It's heavy. And the pictures are great - way beyond what I can get with a PaS. The focus is fast and accurate. The wide open lens keeps the focus on the candids.

I got the best job on my kids' summer swim team using it; no "volunteer" timing or data entry for me! I just have to wander around and catch kids in the act of having fun.
