While I share NOTCOT's worry about the lack of wireless security—and will add my own quibble about someone's inability to reach down and flip a physical switch—the Belkin Conserve surge protector with its wireless switch is a cute concept. Six of the ports on the power strip are turned off when you flick the remote switch, while two stay on for things like alarm clocks or routers. And because the switch has a magnet in the back it can be hung up nearly anywhere, making it as convenient as possible.
There are six separate channels the Conserve can be flipped to to prevent interference, but that won't do much to stop accidental or malicious disconnects of your power by someone with another unit.
