An early Dell Black Friday deal! Dell Small Business offers the Belkin WeMo WiFi-Enabled Light Switch for $29.99 with free shipping. That's $10 under our August mention and the second-best price we've ever seen for a new unit — we saw it for a buck less last Black Friday. (It's a current low by $14.) The WeMo allows you to control your lights from anywhere with a wireless or mobile Internet connection via smartphone or tablet.
