Not quite a mouse, but I use a Wacom Intuos 'Pen and Touch' small tablet. Not everyone has the need for a pen interface, but I find it useful for notes and idea explanation. There is also a wireless kit available for it, but I haven't tried it out. Before my tablet, I used a Kensington 'Orbit' trackball. I liked it a lot, but it didn't last well.(the buttons got soft, the rollers got more and more resistant despite cleaning) I tend to use oddball things like trackballs and touchpads with my desktops because i'm left handed, and I haven't found any decent feeling lefty mice besides semi-uncomfortable ambidextrous styles; plus I mostly just keyboard.
