I don't see what the big problem has been with some people and plugging the mighty mouse in. All the reviews comment that the mouse cord is way too short on it. Well, correct me if I am wrong, is it not the exact same length as the cord on my Apple Pro Mouse. The pro mouse is still my absolute fave and I find it to be incredibly comfortable in comparison to heavier, higher, shorter mouses.
Obviously the cord is not long enough to plug in to a system that is on the ground, but can't you just use the USB hub on your monitor? Seeing as just about the only system that is meant to be placed on the ground is the Power Mac the problem seems moot: any user who was using a Power Mac would also use a monitor with USB connections on it. And any other Apple computer would already be on the desk and right at reach.
