I'm thinking they need to come out with an app/case for your iphone where you can turn it into a pov camera then you can just upload it to the internet and not spend time downloading etc.
(anyone want to do that idea i want some royalties)
also I think kites for skiing could be legit. you could get some more compact kite ski up face pack them up and bomb down. I know they have some of this already but something more affordable and accessible.
I also think there needs to be a new goggle out there. seems like everything has been done and doesn't seem like there have been too many new ideas on that front.
