Actually a couple features of that would be very useful to a serious photographer.
It shows a live preview on the screen and allows manual setting of aperture and shutter speed, and also serves as a remote shutter release.
If you have the camera on a tripod and want to shoot the same scene at different settings (exposure bracketing, or trying different apertures for depth of field), you have to touch the camera to change the settings, then wait a short time to let the vibrations die down before taking the picture. This lets you do it hands-free.
The full auto stuff is worthless to me and most RFF members, but the manual control features would be great.
