When it comes to the mouse, there's basically one design that we all have to get used to. Conform to, if you will. Sure, there's been plenty of variations out there, with some that include more buttons, and still others that have no buttons at all (at least, not visible ones). But, at least to the best of our knowledge, we can't remember the last time we saw a mouse that actually looked like a hand. More specifically, a mouse that fit into your hand, like a one-side glove, and conformed to you, and not the other way around.
