bracketing your exposures, there is no better tool than the D200. You can bracket upto 9 shots at varying exposures from 1/3 to 1 full stop.
For those who love HDR photography, this is indeed a drool worthy feature. My earlier D70 could do only 3 shots in auto-bracketing mode. I still managed to get some decent HDR photos though. I can only imagine what those pictures would have looked like if shot with the D200.
Even if you don't like HDR, the ability for such a wide range of bracketing means that you can enable bracketing for most of your shots and then select the best exposed one. Nowadays, memory is very cheap so storage is definitely not a problem.
In this shot, I took 5 exposures at 1 stop interval and then merged all the 5 pictures in Photomatix software.
