Yes, BUT WHAT IF YOU NEED AN IMMEDIATE IMAGE AND
CAN'T PROCESS THE RAW DATA!!!!!!

THEN I SHOOT RAW+JPEG & USE THE JPEG WITH THE
CRAPPY WB!!11!!!

The white balance needn't be "crappy" if you take a moment to set it with
live view. I've tried it, and it works very well, particularly under
fluorescent light, where a bit of green/magenta correction is needed.
