Let me mention other obvious benefits of IS seldom noted explicitly: It reduces the need to carry a tripod. In turn, it reduces the time necessary to set up a shot. It reduces the need for fill flash because the camera captures the available light for exposure.
The image of the bomber aircraft indoors in the museum illustrates how the available light reaches more of the main subject at the slower shutter speed which IS makes possible. The overhead lights do cast a shadow from the aircraft on the floor, yet the light reflected from the various nearby surfaces reaches under the aircraft to illuminate this subject area. Thus the image more pleases and informs the visual perception.
Brain0: You say, “if you look at the picture of the squirrel, you'll note that the rail on which it is sitting is pretty sharp. If you look at the lines of the wood grain, there isn't any noticeable motion blur.”
This focus may result from using the setting for multiple automatic focus points instead of the center AF point. Using multiple focus points, the camera will sometimes pick a focus point in the foreground, throwing the farther elements out of focus. Hence, this automatic focus action may mimic front focus.
For this reason, when shooting a subject like a squirrel, I will set the AF to the center focus point, thereby putting the focus on the main subject.

oh boy, look what I just gone and did.

Have you ever actually done that? I did that exact thing years ago when first getting into photography, wondering how fast is fast with respect to shutter speed when it comes to both stopping action and camera motion.
