Self-Defeating Devices 101 - classes in "what the?"

Unless there are an awful LOT of devices in your home drawing so-called "vampire power" (i.e. they still draw power even when turned off, as most TVs and audio equipment still seems to do) you might not see the value in this device.  I mean, it has to remain powered up in order to manage the other power points, and each power point where you plug in one of the remote receiver/switch units will be drawing vamp power itself.  Seems kind of pointless to me...
