I think shooting from raw is the best option for creative photography - any work you do on your pictures from the pc via post editing software, will destroy some elements of data from your image, as it needs to compress the files to work on them.
Shooting in RAW allows you to change practically any setting you want (exposure/white balance/ Brightness /contrast) without loosing detail or quality on your shots - it really is simple and you probably wont ever want to shoot in jpeg format again for the images that matter- download a free trial of photoshop or other post edit software to see how easy it is :)

Have a go for yourself, the possibilities are great, I usually set my camera for RAW and JPEG so I have a choice of which to use :)
