What do you think about two different type (CF/xQD) (CF/SD) slots?

Yesterday I was sitting at half time at a basketball game downloading shots.  I had a D800 and D4 shooting, and THREE different card formats.

It's stupid, Nikon was wrong to do it.

But it's not a big deal.  I use mostly CF's and have enough SD and XQD to have backup.

So don't make a camera decision based on it.

But Nikon - get a clue.  Pick ONE.  Stick with it.  If you need to change CHANGE and put same in any given camera.
