Yeah, I understand the whole "it's round" concept. The reason I asked the question is because assuming this uses the same type of interface as a mouse, there is a difference in which way it could be. In other words if installed one way, right is right and left is left. If installed the other way, that could be reversed. I just want to make sure that whatever way I install it, when I spin it to the right, the cursor moves to the right and when I spin it to the left, it goes to the left. So all smart ass comments aside, anyone have any insight or pics of theirs installed? As always, thanks for the help.
