I basically love everything Apple makes, except this damn mouse. It was killing my hand and arm. It's basically just for looks and with no second button and no scroll wheel it requires tons of arm movement. I switched over to this Microsoft one (I know, but it's actually pretty nice). They did a good job on the software for it as well. It plays nice with OSX. Having the scroll wheel has cut down my arm/hand movement by about 60%.

I also got a gel pad. I didn't think I'd care about the mouse being wireless, but it's actually kinda cool.
