Can’t bring yourself to cut the cord with cable TV yet? (btw, it’s exhilarating) Try cutting the cord on your electric lawnmower. The Ryobi 40V Cordless Mower ($399) uses a spiffy 40V Li-ion battery–no oil, no gas, no eye of newt, nothing. It takes just 90 minutes to charge up, giving you plenty of time to make that call to the cable company. Tell ’em Sam sentcha!
