oh wow - that's a great comparison.
the higher ISO, the slightly better IQ, the 51 point focus, sports, color accuracy, 5FPS, higher res screen and build quality are the reasons why i bought the camera - because
THAT'S where i need my camera to be best at
BUT, i'm secretely in love with the 5D2's friggin HD Video
p.s.
the ONLY reason i'm a "nikon guy" is because my buddy had one about 5 years ago.
IF i would have owned a Canon from the beginning, i'd have a 7D or 5D2 with a couple L lenses.
