i know what you mean. i've seen gapers at my local mountain with them and i just thought, 'who is going to want to watch that pov?'
that said, i think that anyone who can readily acquire one should use one, in order to not miss that perfect shot when it arises.
i love having one, not just for skiing pov but a variety of uses; sledding, tripod mounted for my backyard. and i'm really stoked to use the waterproofness this summer for cliff jumping and fishing.
