Ok. Well I like to use the lowest ISO possible, and I worry about handshake!
So even in low light you didnt need VC,
I don't know what people shoot in low light, but for me it is usually night landscapes or city shots, or else people. For the night landscapes, Image stabilization is still not good enough as I am often in the 1/2-10 second range which is too much for it to handle. So I use a tripod. For people shots, you need 1/80 to prevent their motion blur, and IS can't hold a person still. 1/80 is outside of where IS benefits you for a standard zoom (say 55mm or less). So the only time IS really helps on a standard zoom is for subjects and light where 1/6-1/60 shutter speeds are safe. That's just not very many subjects.
And I will also add that Noise ALWAYS looks better than handshake blur. Without exception. A noisy shot is just noisy, but a blurred shot is trash.
