I use a Microsoft Touch Mouse, I have close app, charms, app switch, Start Screen and scrolling setup as gestures which makes navigating W8 a breeze, once you get used to it. The left and right mouse clicks require more pressure than I'm used to and the right click often triggers as a left click. For right click you have to click closer to the right edge of the mouse which is a pita. Overall I like it and it is functional but I think I will be trying the Logitech Touch mouse to compare mostly because of the pressure required to push the buttons.
