I tend to think that IS/VR/VC/OS at longer focal length is more useful.
Think about it, at shorter focal length and a few stops slower shutter speeds than the 1/focal length is very very slow. You will not only be handshaking, at such slow speeds your whole body's movement (not small jerky vibrations) would be recorded in the exposure. You should know what I mean. With IS/VR/VC/OS activated the viewfinder doesn't shake but it does move.
Therefore, it's not really a good replacement for a tripod compared to using IS/VR/VC/OS at longer focal lengths since you would be using a much faster shutter speed.
It is useful, just not very useful.
