For those of you who are interested in getting an "EXTREME" HD video/still camera, this is highly recommended. I got it about a month ago and love it - it takes amazing video and stills. Underwater it is just as good. I have taken it surfing, fishing, camping, to the pool, on my daughter's bike helmet, my inline hockey games, basically everywhere. Things works great.

My buddy here at work just bought one and took the below video of his drive into work on his motorcycle - this looks cool! Great video taken at 60 fps in 720p. Battery lasts 2.5 hours.
