I have a MacBook Pro, running Snow Leopard and I'm using a Magic Mouse which connects through Bluetooth.
While I like the mouse, it's way too slow for my taste. Moving the mouse cursor takes ages. On my Windows PC I'm using a Logitech G9 and in Control Panel of Windows I have set Pointer Speed to maximum with the 'Enhance Pointer Precision' box checked.
On OS X I have set the speed set to maximum as well, but it's still way to slow. I'm used to move the pointer from from egde of the screen to another one with minimal wrist movement.
