The Arc Mouse is packaged almost like cosmetics – in a beautiful, see-through plastic box.

I’m sure this was not Microsoft’s intention, and so I have to say this side button is a major design flaw on an otherwise well designed product. Lefties, on the other hand, (sorry, bad pun), have no such difficulty and can easily use this side button with their ring finger. In fact, the only way to side click is to hold the Arc Mouse “claw” style with index and middle fingers curved, but then normal clicking is not comfortable and scroll wheeling is impossible. It’s at least 15mm too far towards the front of the mouse to be accessible by thumb. However, the placement of this side button renders it completely useless. The Arc Mouse, while symmetrical, appears at first not to be lefty-friendly, as there is only one side button for right handers. Such a shiny finish would seem to imply a lack of scratch resistance, but in my two weeks of travel on trains, planes and in cramped hotel quarters, I’ve seen no hints of blemish. My red sample was absolutely flawless, and has faint metallic flecks in it as well. The top of the Arc Mouse is finished in an extremely high-quality glossy paint with a glass-smooth finish.

Given the overall design, it would be great to see a nicely machined aluminum wheel with a bit more heft – like the one used by the equally new for 2008 Explorer Mini. There are no whiz-bang scroll wheel features, just vertical scroll and wheel click. In a quiet environment, it’s downright obnoxious to fellow library patrons. The rubberized scroll wheel, while easy to use, is only of the basic variety, and a bit “clicky” and cheap sounding for my tastes. The two main buttons fall easily to hand, and click softly, sounding almost exactly like a BMW turn signal. The shape works very well in the hand, and the hollow bottom provides a great place to wrap the non button fingers around for a good grip. When closed, a crouching low-to-the-ground turtle disguised as a mouse. When open, a symmetrical smooth boomerang curve that looks poised and ready to leap. The major talking point about the Arc Mouse is the unique shape. 7 Compared to its Cousin – Explorer Mini Mouse.
