Although at first glance it looks like a cross between a stealth aircraft and a shoe sizer, this Microsoft Sidewinder gaming mouse is supposed to give top-flight players an extra edge over their unfortunate foes.
Like many other mice, you're able to switch its dpi settings on the fly, choosing 400, 800 or 2000 dpi with a quick push of a button. But the Sidewinder lets you see the results of your choice on a small LCD display right there on the mouse, which, contrary to what Microsoft says, isn't the first time an LCD was placed on a mouse.
See that slide-out drawer at the top of this picture? That's where you can slip in up to 30 grams of small weights, giving you just the right amount of heft for maximum fragguracy. You can even choose from three different friction levels, switching out the pads on which the mouse glides to give you the precise resistance you want. All this sophistication will be available in October for $80.
