I use a Contour ROAM HD, but the ROAM2 is (I think) the new one, which can film in 60fps and has a higher resolution lens... Camera terms aren't my forte. But my Contour only has a 5 mega pixel camera, the ROAM2 is much better I think. I assume it has other additional features as well.
There isn't that much difference between the Raom and Roam 2, I think that it has a new type of lens which reduces fish eye distortion and increases clarity, but as far as I'm aware its the same 5mp sensor, oh yeah and you can get it in funky colours
