Well, you got your D80 and have whined a lot about RAW incompatibility,
so it is obvious that the D80 is different than the D200 in at least
that respect.

Most people expected that the D80 would have picture quality at least
as good, if not slightly better than the D200 -- we hope that progress
continues and that Nikon is not deliberately crippling new cameras.
That said, there are some considerable differences between the D80 and
the D200, some having to do with picture quality and some not. Most
notably, the D200 is a lot easier to use if you like to change settings
frequently. ISO, picture quality, white balance and mode all have their
own buttons. The D80 is not nearly so convenient. The D200 is metal and
weather sealed. The D80 is not. The D200 uses the clunky, but
versatile, ML-3 wireless remote; the D80 uses the tiny, but single
function, ML-L3 wireless remote. It really seems to me that Nikon could
have built an infrared ML-3 sensor onto the front of the D200, but that
would probably have added another switch on the back or a menu item to
select wireless remote channel.

If you like shooting in P mode most of the time and don't fiddle much
with white balance or ISO, the D80 is a better choice. If you are out
in the weather a lot, rarely use P mode, constantly adjust ISO and/or
white balance, change lenses frequently, have manual focus lenses,
etc., then you probably want the D200.
