Just got a Go Pro Hero this last weekend. Been using an older Panasonic Mini DV video camera for the last 3 years. My bikes vibrations finally killed it this summer.
Mounted the GoPro on my handlebars and took off with my son for a 250 mile ride through the mountains. Still learning all the features. It's small and lightweight. Just 2 small buttons to push in different sequences to change video resolutions, set features, etc. Small LCD screen will take some getting used to. The outdoor ride video in bright light came out great. Filming some of granddaughters volleyball match came out okay. Wide angle settings have a definite curvature to the video. Playing with it indoors and low light, not so good, but maybe I just don't know how to work it yet. I miss having a telephoto lense.
They don't give them away. $470 @ Best Buy with extra battery/charger, LCD screen, tripod mount, 16g SD card and case.
I also plan on using it while snowmobiling. I think it will work fine.
