David Carr: 15fps played back at 30fps would indeed be "pretty pathetic slow-mo" because it would, in fact, be speeded up.
GoPros are useless in low light and have all the problems of a programmed exposure in bright light because you don't have any control over the shutter speed. No control, as a consequence, over motion blur.
You can't lock exposure either (which would be one way to reduce noise in low light, preventing the camera from automatically "gaining up" when it's pointed at something dark).
The ProTune firmware update helps improve the image in good light but does nothing to improve low light response.
Anyway, at least we know why the ProTune update was so overdue: they were busy making the Hero2 obsolete...
You're missing the whole point of a Gopro. Of course it has shortcomings that larger and more complex cameras don't have. It is all about where you can put this camera, not how sophisticated it is. I think thir biggest mistake will be to over engineer it. The good news is, it is getting smaller, not bigger.
