This has become a very interesting discussion with, obviously, some divergent opinions. If I am understanding it correctly, for those of us with average needs, ISO will do the trick; for those whose needs are demanding (e.g. printing large), the speed becomes critical.

Those are my thoughts...

And yet there are some programs such as MacPhun's Focus2 Pro which allows doing somewhat e simulation of shallow DOF in post processing. It won't necessarily give you the exact result you would like, but it "ain't" bad.
Perhaps what I am reading is that the technology could be changing the conventional wisdom about lenses. Perhaps alternate tools are starting to replace the concern for speed?
