FYI and FWIW - Lightroom currently has the Beta version for the S90.
One thing that sticks out is that when you import into Lightroom, the wicked barrel distortion that I have seen (and reported on) is non existent in DPP. It may be a software fix that recognizes the camera and applies some software fixes to the lens' focal length.
Either way, the photos look a much better in DPP.
