I shoot RAW only 9 times out of 10, mainly because I still need a USB card reader as the 350D gets funny about the RAW and JPG on the direct camera USB. I have a card reader on my pc downstairs, but its kind of not fitted and just goes into a usb header on the motherboard.
RAW + Fine JPG is the best way to shoot especially if you have a slow computer, you can skim through the jpgs to sort out the rubbish shots, then only pick the good ones for RAW processing.
