What I like about this whole discussion is that the title is "is raw really worth it".
What's the expense? I can fit about 120 12.4mp raw files per 4gb of storage. Thats like four rolls of film in about 1/10 the physical space. Flash memory is at most, like $4.50/gb, or about $0.14/image.
There's time in processing, but if you batch process this is maybe 2 minutes per image, including data transfer which you have to do anyway. So yeah, it takes a little more time to process SOOC, but typically RAW processed images have better resolution, sharpness and flexibility - in case you, say, you forget to switch from daylight to incandescent - you'll have majorly screwed up the entire Wedding Reception. And if they had tungsten corrected florescent lighting, who friggin' known what the color settings should actually be - do you really trust your camera's goofy color meter to get it right?
