Anyhow, here is an additional thought in regards to the placement of the green button.
It has been said, and I have said, that the placement of the green button is stupid silly. My attitude on this has really unchanged. In fact, it really pisses me off,
since I use it quite a bit. This button should have been just to the right of AF/AE-L button. There is even an empty space there. I could have accessed with my thumb. How lame.
So, in the past few weeks I have developed a new technique to deal with this nonsense. I began using my middle finger to press the shutter button, so that my index finger can reach over to the green button. My thumb is consequently placed (no not up my ass) at the bottom of the camera, just below the LCD screen. A bit awkward at first, but now getting used to it.
