I am thinking about buying one...I have a Canon SD1000 and it does okay for point & shoot stuff, but the audio sucks.

Here's a clip of my Forester's exhaust (Maddad Whisper) - notice how bad the audio is..and that's without wind noise compounding the problem:

I'm looking at this..would be a lot of fun for car/bike/snowmobile/etc.

I have one (Youtube destroyed the quality, but I got it up to 720p I believe)

I have one of these. http://contour.com/camera/contour_hd I've used it to video some track cycling ie http://www.youtube.com/watch?v=yHUVlumcKK0

I love the size and shape of the contour, I really wanted to get one but I just couldn't stand the really wide view angle it has, everything looks fish eye'd.. In some cases you might want that but I couldn't deal with it.

hey zardini did you win your mario cart race

I dont even know what to say (No I didn't win, I missed qualifing that morning because the day before it was rained out, so I started last on the grid 12th, and finished 5th..)

Yeah, the fish-eye thing is a little annoying, but overall it doesn't affect me too much.
