By your comments, you implies that Nikon is crippling their camera by implementing 2 fast card slots. So do you see 99% of Nikon users disagree about putting in a fast 2nd card slots? You can’t have it both ways. You either think Canon is doing it correctly or Nikon is doing it correctly. Clearly they are both doing something different. Pick one. You can’t have your cake and eat it. If you think Canon is doing it the right way, then Nikon must be wrong.
