CNet points us to the Belkin Conserve Surge Protector which shuts down 6 of its 8 outlets completely with a remote switch that you can mount by/like a lightswitch. The idea is pretty simple but can you make it work? A lot of devices require always on-functionality. Cable Modem, Router, etc. Plus, all Macs are pretty good about going to super low power mode when idle so is the cost savings worth it?
