I liked my Lumix a lot (it got stolen in Canada, of all places) and even went swimming in the Mediterranean with it, but it was still a general purpose point-and-shoot. GoPros generally have wide-angle lenses and I don't doubt they're even more durable. It makes sense to me to make a product that's as tough as possible, just to make sure they're not going head-to-head with Panasonic et al.
