Query: Awkward, only in a different way

I found the position they thought was neutral for the hand to be quite awkward. A stick that just stands straight up in the air would have been more comfortable, but this stands forward and to the left. Also it's very difficult to use the mouse without hitting the finger button, which on a Mac does something totally random. That button should be much smaller so you don't accidentally hit it every time you grab hold of the mouse. Furthermore, since you rest the weight of your hand and arm on it, it would have been better if the bottom platform were padded like a mousepad.
