@Richard: Are you sure the "last AF is on the shutter" ? Because if I aim at something white and the AF-light strobes and the AF just sits there and I press the shutter, it does NOTHING, but if I release the AF-ON in the same no-af possible situation, it tries again.
Yes, if you have them both set to Auto-Focus (AF-On, not AF-Off) then release AF-On, then the last button that you press (Shutter Button) will set the final focus. If your white target didn't move then the shutter button press had no reason to change focus. Try focusing on something else to test it.

Ah, okay... So I set the shutterbutton to meter when pressed.. Yeeeeah, well then I guess it might not be for me then, just because, If I want to shoot a shot in One shot, I first have to press the m...f..n button to switch to One Shot from Ai, then push the AF-ON button on the back, hold them and then push the shutter. To me, using three buttons to take a picture is ridicolous.
You can just press and release AF-On to stop focus for a stationary photo. So, you don't have to switch out of AI Servo every time. if you would like the AF beep and confirmation then you would have to switch to One Shot. You could also set up different Custom Shooting Functions for One Shot and AI Servo. Personally, I wouldn't let One Shot be the reason that you don't use AF-On for tracking and the shutter button for image capture. I'm rarely in a rush when I use One Shot and you could always change the setting via AF Mode, so no need to hold any extra buttons in if you don't want to. But, do what you feel comfortable with.
