Unless one is an avid photographer of brick walls, basing the lower limit of "acceptable" shutter speed only on the steadiness of one's hands is not a wise approach. Even "stationary" objects like leaves, clouds, people etc. are not all that motionless, and even the best VR will not change this. One ought to make full use of the excellent iso capabilities of the newer camera models and avoid low shutter speeds, unless one wants to intentionally introduce blur. Maybe I am overly conservative, but I try to keep in most cases the shutter speed not lower than 1/100s though I have rather steady hands. Consequently, my only VR lens is the Nikon 70-200/2.8.
By the way, I have not produced a blurred capture in quite a few years, except when I made a mistake related to focus or DoF.
