A power plug that can remotely manage all your appliances

Want to take the power back from your, uh, power bill, but too lazy to manually turn off the electricity hogs in your crib? Pick up some MeterPlugs -- new Bluetooth-enabled adapters that not only measure how much whatever they're plugged into is costing in dollars via a dedicated smartphone app, but can also be programmed to cut power from the wall when you walk away (assuming you're with your phone) or it reaches a pre-selected "running cost"
