I think the most use of it, is in connection with Light control.
I primerely use it for turning on the lights when I get home after dark, or to switch everything (Sound + light) off, when I leave the house. I may not be of much use to those who does not have light controllers. However the all off cannot be replicated by the Beo4.
Maybe the Beo5 can be programmet to include an all off button.
