I'm looking for a new mouse to replace my aging MX-500, and I saw this baby, the Razer Copperhead. How large/small is this thing? I have pretty small hands, so I'm hoping it's not the size of a typical MS mouse like the Habu. Also, how's the durability? I've only had my Logitech for a little more than two years, and it's looking pretty torn up (works just fine though).
