If you are able to get proper exposure and white balance I just dont
see the need for RAW. You can do wonders with JPGS in Lightroom. If
lighting is tricky I can see why someone could benifit with RAW. I
will shoot RAW in those conditions. Mojority of the time it is easier
to deal with JPGS. I think in the Ops in camera JPG if it was not
over exposed the detail would have been there.

Jeff.. enjoying my a700

I'm not sure it's a simple matter of over-exposure as you suggest. The A900 tends to under-expose (and I simply took the shot with matrix metering without any compensation). If the exposure was reduced, you'd lose detail in the dark window area... but the RAW allows you to capture detail in both the bright and dark areas rather than sacrificing one for the other. To further make the point, here is the image and histogram of the cRAW in default view in Picasa... some 'blowing out' in the red channel but overall exposure is fine (see the 'brown' area in the histogram).
