Core77

The design of mice has come a long way: check out Microsoft's nutty new Sidewinder mouse, designed specifically for gaming. Features:

- interchangeable weight cartridges, to give the mouse user-desired heft
- interchangeable feet, to give the mouse user-desired level of “glide”
- buttons to change DPI on the fly
- LCD readout to display DPI
- cable management system
- extra-wide, metal scroll wheel for increased control

While some of the design features may be lost on those of us that don't play Halo and Warcraft,
this is without a doubt one of the most heavily designed mice we've seen. Check out the product page here.
