I agree. I generally shoot in shutter-speed mode since I like taking low-light photos, and in that situation, my ability to hold the camera steady at a slow shutter is the deciding factor.

Where quantity of light isn't an issue, and where I want to create a certain effect with depth of field, as you said, aperture mode is more than adequate, with the ability to change exposure and cap ISO, and let the camera figure out the best shutter speed.
