So I got this new Hero 3+ Silver to replace my old Hero HD model. I really love the new camera. Sound quality isn't quite so good, and medium and narrow FOV modes are probably useless for most applications, but everything else seems to be much better. I can record in a higher resolution format, and at more frames per second. The wide angle is way less "fish eye" and renders a more accurate view of what I see as a I ride over the countryside. The latch hinge is actually attached to the case, so it can't just fall off. The buttons are larger and easier to operate, so that I turn the camera on and off, even with my gloves on. And the camera beeps are loud enough, that I don't have to shut the engine off to hear the camera power up and go into the chosen mode. I'm pleased.
