Belkin WeMo Insight Switch
The Belkin WeMo Insight Switch ($59.99) won't actually help you work faster, but it may save your from turning around to check if you've turned off the iron or space heater. Like the other devices in the WeMo family, Insight Switch lets you use your iOS or Android device to remotely toggle connected electronics on or off. More importantly, the Insight Switch adds the capability to monitor the energy usage and offer an estimated cost for your energy bill. You can then see, for example, if you kids have exceeded their daily TV limit, or if it's really worth turning on the heater again.
