The Gopro is an unbelievable camera.  It has a tiny footprint and the video quality on my Gopro HD Helmet Hero is unbelievable.  It’s made to mount anywhere and everywhere, so you can be creative as you want and film everywhere.  As far as a wearable camera or helmet camera, I have yet to find one on the market that is better.  The only slight complaint I have is battery life.  I get about 2.5 hours of filming when on the slopes, but I’m usually out there for 8 hours at a time.  I love to film everything.  Gopro is launching at Gopro Bac Pak that will plug into the expansion port, but I suggest that when you order your Gopro get an extra battery for $20.
