One of the main reasons I shoot RAW is the ability to work with the white balance of the photo. If your white balance is off, it is much easier to correct when convert the RAW format, then working with a jpeg (or tiff) As stated before, if you shoot a high contrast scene, where if you lose detail either in the highlights or shadows, it is easier to correct when shot in RAW. Just convert the photo twice, one corrected for the highlights, one for the shadows. Then in photoshop it is fairly easy to use a layer mask to get correct exposure for the photo.
