Look what the mail truck dragged in! After first announcing the X8 in early September (where we got our first look and photos of the mouse), Microsoft has finally shipped the latest addition to the Sidewinder gaming mouse family. The X8 adopts Microsoft’s proprietary Bluetrack technology, which empowers it with 4000 DPI tracking resolution (scalable from 500) and the ability to work on almost any surface. We tested this claim on five different surfaces, from a rough wood desk to Styrofoam board and even coarse carpet. The mouse worked fine (though understandable not perfectly smooth) on all of our test surfaces, and only failed when we tried moving it over glass.
The shipping version doesn’t differ much from the pre-production model we fondled back in September, and retained the nice grip and smart button placement that we liked from our first hands-on. The included rechargable battery was a cinch to install, and tethering the mouse to the thin magnetic cord didn’t hinder our sweeping mouse movements. The wireless receiver is built into a clunky puck-like disc that sits on your desk, which ensures that you get better reception than if the receiver was hidden on a USB key behind your PC. The X8 still feels big for some hands, but our initial impression is that this is a winner. We’ll post our full review soon, but for now, enjoy these sexy unboxing and handling photos.
