whew, so much discussion over one wheel or two, one knob and a ring. I use whatever controls a given camera has. The human body is mostly adaptable, the human mind should be *infinitely* adaptable. ;-)
I tend to prefer the "set the aperture and shutter speed" from the body, and one wheel as in the *ist DS works well, two wheels as in the Sony R1 work well too. Never really liked the *ist D, Canon 10D style two wheels ... I always forget which one does what and hit the wrong one every time. The R1's two wheels are both thumb wheels and have sensible placement to make it easy not to forget which is which.
