Mobile World Congress, Europe's biggest mobile tech conference, was the site of Nokia's ruthless mining of the world's natural megapixel reserves. The Finnish company (who's lately started making phones we really like) announced the 808, a smartphone with a 41-megapixel camera, along with a sensor and flash big enough to feel at home in a point-and-shoot. That'll give the phone better digital zoom capabilities and hopefully better image quality - Nokia has a new system to take all those pixels and turn them into nicer, smaller pictures. (Oddly, the phone will use, of all things, the very dead and very awful Symbian OS.)
