It is indeed bulkier when mounted on a helmet but you can mount it on the handlebar, chest, etc., if this bothers you. The controls do indeed take getting used to but after a while you get accustomed to it.
EDIT: Here is a sample video from my 2 GoPro cameras (one mounted in the drops and the other one facing to the rear on the seatpost):
As far as the grade and speed extra goodies. How did you guys/gals come up with this? Is it a feature built-in to the camera or do you need some other "magic"?
