Ok gang, i just re-checked the keys (this time with glasses on) and believe it or not, Donny's correct, there's indeed a thin metal (aluminum) weight of some sort glued to the bottom of the front section of each key. The function of this is not as a counter weight though, but to provide STABILITY to the front portion of the key, as without this, the thin plastic front section of the key alone would feel rather flimsy. I think perhaps there still may be 'counter weights' mounted under the mid-rear section of the keys to provide the resistance to finger pressure at the front, but of course can't substantiate that. - Scott
