Do you shoot RAW?

[pixelstix]

I'm getting ready to teach a digi class and I'm writing up my notes. Since I'll be showing them how to quickly edit their photo's exposure, etc. in Adobe RAW (my preferred method), I need to quickly explain what RAW is. And since I'm bad at explaining stuff, I did a quick google to help me get the words right. I came across a Ken Rockwell article where he talks about shooting in RAW like it's the dumbest thing you could do. I know I've heard this all before, that you don't need to, and I know you can open your jpgs *in* RAW (one at a time?) but I've always seen a noticeable difference from my camera between the RAW file and the JPG (I shoot RAW+JPG) so I've continued to shoot in RAW and fill up my hard drive.

What do you do?
