We believe in putting GoPro cameras on pretty much everything. Corroboration and sharing of awesomeness breeds more awesomeness. At first glance, the Proview GoPro Cell Phone Mount seems like a ludicrous invention. Do you need to capture your walk down the street? Is it really necessary to have a GoPro record your texting? Obviously not.
But the point really isn't about capturing your life from your phone's point of view—it's that you now have a live-view screen (your phone!) attached to your GoPro, turning it into a useful camcorder.
