Raw is better for image data BUT loses the camera's internal automatic chromatic
aberration and geometric distortion correction. This results in poor images
thanks to the optics of a typical PS. ELPH/IXUS and S3IS both had lots
of optical issues visible in the RAW files.

You can address this in Photoshop CS5 by creating a camera profile using
Adobe Lens Profile Creator (ALPC) and shooting calibration images in raw
mode using CHDK. This is surprisingly time consuming AND due to the reduced
sensor quality ALPC rejected
I have 3 point and shoot Canon's for which I use CHDK
I used the raw shooting capability to shoot CRW format images. These
require processing with DNG2PS or similar to import the EXIF data from the
matching JPEG and convert them into a usable DNG format.
I've learned by reading this thread that

This might be true, especially since raw takes far longer to process.
However, raw is

No, it doesn't. The files have the extension .CR2 but it's CHDK raw that can
only be read by very few programs and doesn't contain any metadata.

I don't understand your point. I agree that RAW without any metadata is very
limited, but DNG seems OK to me. I don't see where JPEG is better

After some preparation CHDK can also write DNG format,

Anybody use CHDK? How do you like it? What is your experience with it?
Good. I use mainly bracketing and seldom (not panorama related) motion
detection and timelaps script. Sometimes I shoot DNG (which *has* all
the EXIF).
