Controlling the DX/FX controls is one of the best features of owning a Nikon D800.  With this function at your finger tips any photographer can quickly frame and re-frame a subject at a press of a button.

The crop factor when used on an inexpensive lens like the Nikkor 50mm 1.8D turns it into a 75mm lens more suitable for portraits. A longer lens is useful when you want to step away from your subject, or to tighten the framing around a specific subject in a group gathering.
Another great technical reason for having the FX/DX switch is the ability to use the sharpest part of the lens glass. It is not unusual for the centre part of the lens to be the sharpest at certain apertures. By using the DX crop and and  framing your subject within the crop lines, you are staying away from the soft edges, especially important in portraits. Using the crop factor in this way makes maintaining sharpness throughout any photo shoot session effortless.

I customize my D800 with FX/DX button + command dial. It makes for a quick operation without taking your eye off your subject. See Page 79 - Image Area, in the D800 English manual for more information on image sizes of the FX, Square, DX, and 5:4 aspect ratio offered by the D800.
