If you're one of those people that prefer using the trackpad on your laptop over a conventional mouse, Apple has you covered. The Magic Trackpad is basically a MacBook trackpad sold separately. That means, when used with Mac OS X, you can use it just like you would a multi-touch trackpad on a MacBook: swipe, scroll, pinch, and expand. It's surprising comfortable, too. We've yet to test it, but Logitech makes the Wireless Touchpad for those of you on the Windows side.
