I'm using a Magic Trackpad on my desktop and the regular 4530s trackpad on my laptop, it might not be as amazing as the Magic Trackpad, but it does it's job. If you really want a mouse that properly works with OS X gestures, it would be a magic mouse, without a doubt.
A great tip before you start thinking about buying any of those above: The built-in bluetooth that comes with the 4530s is not compatible with the magic mouse or magic trackpad. I have not heard of a single person who have managed to pair these devices with the built-in bluetooth without having extreme mouse-lag, gestures incompatibility and constant disconnects. If you want them to work you'll need to buy a compatible bluetooth dongle or install a MacBook bluetooth inside of the 4530s.
