Review: "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.
The GoPro Digital Hero 3 is a cool idea for a camera, but in action, it simply isn't very good. It's a sluggish performer and shoots soft, small images. That said, the wrist-mounted, underwater housing is a great boon, and it might prove a fun, inexpensive alternative to swimmers and other water-dwellers who want a camera they can submerge."
