Well, last year I had my camera mounted on my dash. My camera is kinda heavy, and it did get a little shakey at times. But even with the shaking, the video was still decent. You can see all the Moab videos I took posted on YouTube.
If I get lipstick cams, I will either velcro them to my roof rack, or possibly attach them to some rare earth magnets so I can stick them to my VX wherever I want. Since these cameras are so small, they will be perfectly stable. That is why I want to use lipstick cams this year instead, plus I can mount them on the exterior, which should create some interesting view points.
