Engadget - GoPro's lineup of mount-anywhere cameras has been dazzling extreme sports enthusiasts for years. The original HD Hero first delivered stills and wide-angle HD video in 2009, and those capabilities improved with a higher-res sensor, faster burst mode and a wider field of view in the Hero2. Now, GoPro has rolled out the Hero3, which packs even greater performance (up to 4K video!) in a cube that's almost a full centimeter thinner than its predecessors.
