since my family lives so far away, we celebrated christmas over thanksgiving. so they all chipped in and got me the hero HD camera:
the video is really good, but it seems to have a hard time showing details in shadows. there is an exposure setting so i will have to play with that to see if i can get more detail in darker areas. the audio comes across pretty good too, but you can easily pick up wind noise. there is, however, also a full enclosure case so i think that would block out some of it. i picked up a 32gb sd card for the camera, but i may have to get additional cards. 9 minutes of video took about 1.5gb so thats about 192 total minutes of video. although... thats longer than the battery lasts.
anyway, here are some videos of the camera mounted to my rc rock crawler and on my tacoma.
