A camera, digital or film, is just a tool. It's up to the photographer to learn how to use that tool properly. You can't blame the tool because the person wielding it doesn't fully understand its operation.
Now, I don't have an Olympus m-4/3, but I do shoot a mid-range Lumix. If your intention is to shoot high-ISO, and you're concerned about shutter speed, then set the camera to shutter speed priority mode instead of aperture priority.
I've understood there's a "super control panel" feature with Olympus cameras that might make the menu system more tolerable.
Good luck and keep us posted.
