True...but, I strongly suspect that the great two-card slot debate gets a lot more attention on this forum than it does in real life. It would be interesting to see how many photographers actually set their cameras to shoot and save to both cards. I suspect it is like AFMA. A lot of photographers know they should probably do it, but very few working pros actually do.Even the very best storage mediums can fail. Having two standard cards is much safer than having one very expensive card.
