Having said that I rarely use raw capture, there are times when it is worthwhile. I recently visited Ely cathedral, without a tripod. The roof is a long way up and it's pretty dark up there on a dull day in Feb. I attach a crop of the picture taken in jpeg mode.
The same settings, using raw capture and Adobe Camera Raw to process, you get this:

I was quite surprised by the difference. I'll still only use it when I think it's really neccessary but bear in mind that it's there when you need it.
