My D40 is flawless in AUTO WB mode outdoors, and utterly hopeless indoors (with artificial light, that is).
However, I shoot RAW so WB is not an issue for me..
In the very rare cases that I don't shoot RAW, I leave it always in Auto when outdoors, and set it manually when indoors with artificial light.

I believe that most digital cameras are less then perfect when using Auto WB....I also shoot 90% raw so no not then, but when shooting jpeg my KM A2 is hopeless then yes...always.Fred, KM A2 and F30'Your best Photo should be viewed with a biased eye'http://coolsiggy.smugmug.com/..
It really depends on what kinds of subjects you shoot..
For example, outdoors I shoot mainly landscapes. During different lighting conditions, for example stormy clouds, or sunsets, the one thing I definitely do not want is the auto WB control to intervene and neutralise what I am trying to capture. So I mostly use a fixed pre-set WB for these shots..
On the other hand, when my pictures include people as the main subject, my priorities are different, I want a more neutral rendition of skin tones, so auto *might* be the most appropriate setting..
Indoors, things are different. If the lighting is mostly tungsten, I choose that setting. If using flash, I choose either flash or daylight pre-set. But sometimes the lighting is a combination of tungsten and flash. The auto setting works best for this..
Other subjects benefit from a custom white balance. Particularly macro shots, or copying of paintings and pictures, I set the WB manually using a piece of white card as the reference..
But there is no definite answer. Say for example I have an old black ink drawing on white paper. Do I choose to render the white paper as pure white? Or to capture the fact that the paper has turned yellow with age? Both are correct, it is a matter of choice.Regards,Peter..
What AncientMariner said..
My camera (Pentax K100D) does a good job in day light with auto WB. But for fluorescent or tungsten lights it needs to be set separately. if you shoot RAW it doesn;t matter, you fix it later..
I used to use the auto white balance when I first started shooting digital, but I found I didn't like the unpredictability of it. Maybe it's just a hold-over from shooting slide film for so long, but I'm much happier using a set WB setting so that I'm more certain of how the camera will see a scene...
I used to think just fixing it in RAW later was fine, but more and more if I'm indoors I'll set the WB - maybe meter off someone's white shirt or something like that. And then when I go to process the images they have a consistent look, and it's one more thing I don't have to fix..

Even outdoors, I set the WB to Sunny or Cloudy. On occasion, I use auto WB but try not to...
