I would say the GoPro there both really good but the GoPro has way more
mounts and in the the new GoPro 2 it can slow it down to 120 frames per
second and the contour cant do that i have friends with both. the
contour is a lot easier to turn on and is a little slimmer but it gets
your helmet in the video which doesn't look nice. Also the GoPro has
alot more ways of filming and yes you can mess with your lens angle from
your iphone but overall i think the GoPro is better.
