Panasonic's new disposable batteries, called 'Oxyride,' look fantastic. PC World tested some and got over twice as battery life over a set of Duracell Ultras, which coincidentally enough cost exactly the same. It sounds like we've got a new favorite battery. (Thanks, Gordon!)

Update: Come on, hippies, I'm not advocating buying these in lieu of rechargables. But sometimes you have to buy throw-aways, and when you do, these look great.
