There are certainly times in which the white balance of the light illuminating your subject matters. That is when you are shooting under a mixed lighting situation, say: part of your image illuminated by fluorescent light (often the background) with another portion of your image (often the closer main subject) illuminated by electronic flash...
Despite the ease of adjusting your color balance in camera RAW, you can have a devil of a time adjusting for that mixed light situation. That is when it may be best to filter your flash to match the color of the florescent lights (usually with a green filter) and then adjust the color balance of your image globally in Camera Raw...
Another thing, if you are shooting in daylight and have chosen a tungsten color balance (even when shooting RAW) the image you may view on your LCD monitor will be skewed.
Additionally, if I select an inappropriate color balance in shooting RAW, it will open in Camera Raw skewed to that color. As an example, it will look very blue if I have set the camera to tungsten and shot the image in daylight. Of course, it is easy to compensate for this but, IMO, using the Auto white balance brings me closer to the optimum right from the start...
