*Full disclosure; I own the Gopro3-Black and an original HD.
While product development/improvement is great, Gopro are a right pain- they bring out endless products, which while great have so many annoying bugs (Cameras freezing, picture artefacts, usability problems etc etc) which NEVER get fixed, it’s just onto the newest greatest product with a new set of problems.
If I’d realised just how bad the battery life on the black was I’d have never purchased it, I was just getting bored of corrupted videos from the HD1 despite the latest FW and no end of different SD cards (All of which Gopro themselves had recommended at some point).
