The new SideWinder X3 Mouse is now available for preorder on Amazon.com (or at least we’re being told it is – I can’t find it yet, though) It will, however, be widely available in May in many locations, including http://www.microsoft.com/hardware. This eight-button mouse is designed for gaming with its 2000 dpi laser-tracking and on-the fly-switching between low, medium, and high sensitivity. Yet it’s still affordable enough for everyday use at only $39.95. But the best part? It’s for lefties or righties! You see, the X3 is the first ever ambidextrous mouse in the SideWinder series. Seems pretty cool, but I’m with Larry – I think if I had my pick, I’d go with the Arc instead because of its good looks and portability.
