I think Nikon tried to make "advance, focus, shoot" a selling point. Not sure it got them many sales.
I do like using the lever rewind one-handed. I never bought into the idea of using my middle finger to focus while keeping my pointer finger on the shutter release. Most of the time, I use my pointer finger to focus, then bring it back to the shutter release. However, if I'm following some critical action and waiting for a so-called decisive moment, I have used my middle-finger to focus so that I can shoot at the correct instant.
