Coolness is a funny thing, because it sometimes doesn't have anything to do with whether or not something is actually good. Base jumping is cool, but it's not necessarily a good idea. The Die Hard movies were cool, but they didn't win any Academy Awards. The GoPro Digital Hero 3 is a cool camera, but it's not a good one.
The tiny, 3-megapixel Digital Hero 3 fits inside a waterproof enclosure mounted on a wristband. It's purportedly a wrist-mounted camera for extreme sports such as snowboarding.
Barely larger than a pair of AA batteries, the camera body consists of a tiny, gray box. It has just two buttons and a monochrome status display, making it one of the simplest cameras we've seen in years. The only way to frame a shot is through the tiny viewfinder, which becomes completely obscured when you put the camera inside its waterproof enclosure. The clear plastic case is quite well made and hooks onto a foam-rubber-and-velcro wristband. Tight seals make sure the box stays waterproof so the camera inside doesn't drown, while two buttons connect to cameras' buttons.
