I agree, as I myself have always used JPEG and have yet to shoot in RAW. However, at the time, I knew nothing of the other types of files.
That being said, I wish I had. There are so many photos I've taken that I wish I had more room to play with. To go back and change the WB on.
So in that regard, I'm actually torn here. In a way, I do agree with Doodle. But I also don't.
