The thing is as stupid as Go Pro's look, they are, from my research the better camera. I have been super happy with mine. The other point I will make is that pretty much all footage done from a helmet, unless filming a friend is boring as fuck to watch. So a GoPro on a pole looks just fine imo. Another thing to consider is that Contour has already failed once and almost never came back, how far are these other companies away from failing with all these new big names coming into the market, Sony, etc?? Lastly, I doubt you will find more accessories for other cams than you will for the GoPro which will make it just as fun to use outside of just snowboarding.
In closing I will say I am not a GoPro fan boy, just look at my avatar, I had the Contour +2. I got wind of the company eating shit and sold mine asap. I did a ton of research and this season I did buy GoPro.
