I bought a bluetooth mighty mouse for my laptop because I didn't want a receiver sticking out the side, but the nano is so tiny it wouldn't bother me. The VX serious seems to offer a more diverse set of options which I would enjoy taking advantage of.
actually i'm pretty sure it does, its just disguised. It is called the MicroGear Scroll wheel, about halfway down the list. Now I have no idea what that means, but sounds fun, and more interesting than a basic scroll wheel.🙂
