Finally managed to get my hands in the Magic Mouse. Looks and feels great but sadly is quite useless out of the box.
Some links that would help to make it work properly:
Middle click allows you to tap the mouse with three fingers to activate expose, this also allows your to do the same on the trackpad

BetterTouchTool is the only application you actually need, replaces the need for Middle click and allows you to get your mouse to do anything you want
