As far as the squirrel shots in this thread, the first one is a classic H-series AF snafu. The camera looks like it focused on the fence, which is the area of highest contrast. This is typical; this morning, my H1 AF had a love affair with some birch catkins behind a bird I was trying to shoot. The spot focus area is not small enough in general; plus the camera can actually hunt so far as to throw the foreground subject completely out of focus and lock onto contrasty detail behind it. It doesn't happen all the time, but it does happen.
In addition, yes, 1/60s is not enough to stop motion on an active animal. The head moved more than the tail here, which is why it appears blurrier even though it is closer to the focus point. In my tests on birds, I found progressively more feather detail at least through 1/400s on a small perched (but active) bird. Worse than that when they're really moving. IS reduces camera shake, but doesn't do a thing for subject motion. In fact, it should probably be turned off when trying to pan, which is the only way to keep up with a moving subject like this. Canon has a "panning mode" IS; not sure how effective it is. The second shot looks like it focused on a background element, too.
As far as the images themselves, there's a lot of smearing and some noise visible. The colors look very weird and harsh. Exif isn't included with these images, so I don't know what the settings were. To be frank, they look like ISO 400 from my H1, which I would only use in an emergency situation. Out of 20k+ total shots from my H1, I've only kept two that I shot at ISO 400, and one of those was a mistake that turned out to be artistic. The other was in a bad situation anyway, and I needed to get a higher shutter speed to try to stop motion so I fired a burst at ISO 400. Otherwise, ISO 200 always won when I shot at both settings. The H2 and H5 seemed to have improved high-ISO performance by about a stop. That's not to say one couldn't get a noisy-looking image at any ISO with inappropriate settings and why it's really hard to judge a camera from pictures one didn't take oneself.
The H9 appears to have entered the Panasonic zone, where the camera's processor is doing things to the images that aren't always for the better. It looks like some of this can be minimized by choosing correct settings (I wouldn't trust my H1 on full Auto in 99% of circumstances; especially when you go to macro or full tele, the disposable-camera model doesn't apply anymore). There's probably some sample-to-sample variation as well.
