While I don't know about those specific ones a friend of mine has a pair that will take a short video and pictures and he is quite happy with them.  They don't take the best of pictures but they are nice enough to share with friends that wonder just what he sees out in the hills.  But that was several years ago and I am sure that they have gotten better. 

My only problem that I would see with something that combines two technologies with one instrument would be if one or the other would break or if the optics side would go bad then what would happen with the camera part? 

I wonder how many of those will be used for less that honest perposes.  You know, guy walking down the street, sees this girl, "click" on goes the video.

I would be interested to hear from anyone that has tried them (hunting).  Seems like a cool idea, but like you said Mike, maybe too good to be true.

I would have to see them being used first as it seems that it would make for a pretty shaky picture while you are moving around. We move our heads a lot just by looking and talking. when holding a camera in your hands you're more aware of this and keep it under control.
