In addition to other reasons folks have given you, back button focus allows me to use my thumb and keeps my index finger useful for the shutter alone.  I have a tremor in my hands which sometimes results in an inadvertent refocus of a scene.  That never happens when I can use my thumb for the focus.  I find it especially useful when shooting in Servo mode.
