I agree! Except I *do* use it for concert photography, all the time. It beats my old 6MP *istDS for this - comparing images at the same size, the K200D gives me my choice of less noise for the same level of detail, or more detail for the same level of noise. From what I've seen, the K20D is somewhat better, but not a whole stop better as is sometimes claimed. It's difficult to compare because so much depends on the specific scene, the lighting, and the exposure, but when I see comparisons that attempt to match these, the differences are surprisingly small. And the K200D has some advantages over the K20D, too, such as better metering with manual lenses (which is very important to me). I also like the smaller size and the use of AA batteries, although I recognize that others have the opposite preferences.
But for whatever reason, a lot of people didn't "get" the K200D when it came out; some still don't. Too big and expensive for the entry level class, not feature-rich enough for the "prosumer" class (whatever that is). The way I see it, though, the K200D pretty much nailed the very large middle ground between those classes. It's main problem, in fact, is that there was so little in that class to compare it to - it pretty much had the field to itself. It actually would have benefited, I think, from competition in that class, because as it was, people would tend to look below or above it.
Anyhow, a couple of recent concert images (ISO 1600):
K200D, M135/3.5:
K200D, M100/2.8:
