Regarding the Flip, you have a pretty good sample just posted recently by Greg in the Trip Reports forum (Killington). I think that the video on that Flip is very shaky. I don't know if it has image stabilization or not. But compare that to my video from MRG in the Trip Reports section in which most of the video with Nhski (the first posted I think?) was taken somewhere in the 15-20x-ish zoom range free hand with OIS.
What was the MRG video shot with? Looks good, but probably outside my price range.
