I have been playing with the GoPro Hero 3+ for some months now.  My first real exposure is with the DJI Phantom Drone.  Here is some early practice footage: 

Recently, I went skiing in Colorado with old friends.  I think we have been doing this for over 20 years.  We had a couple year hiatus but were back at it again this year.  The conditions were incredible, some of the best we have ever had.  This year I brought the GoPro and wore it on my helmut for a couple of days:

While it looks a little funny, you forget it is on.  The only issues I had were in turning the video on and off.  The beeps aren't very loud and hard to hear outdoors.  But, with help, we were able to keep it recording while we skied.

When I got home, I put the following video together to share with our group.  I continue to be impressed with the quality of the images.  I think it does give you a feeling of what it is like to be there.

Clearly, video is not a competency of mine.  In fact, I find it quite time consuming compared to still photography.  But, I do try to shoot short sequences when I go someplace cool as the addition of motion over time shows an aspect of a place or subject not possible with still photography.
