Microsoft has come up with a unique new product in the Arc Touch Mouse, thanks to its clever, convertible design and its touch-sensitive scroll wheel. Like the original Arc Mouse, and the Philippe Starck-designed mice before it, the Arc Touch Mouse is mostly a fashion statement wrapped in a few interesting features. We would still opt for a more traditional mouse for day-to-day productivity, or even for travel, but the Arc Touch Mouse will appeal to people with an eye for design or technical novelty.
The Arc Touch Mouse hasn't been Microsoft's best-kept secret, with hints and leaks popping up online all summer. Despite early assumptions that arose from those leaks, we don't believe Microsoft is positioning the Arc Touch Mouse as the answer to Apple's Magic Mouse. The two have a passing likeness in that they each rely on touch-based input to varying degrees, but the Arc Touch Mouse is far more traditional than the Apple design in terms of its functionality.
Unlike the Magic Mouse, the Arc Touch Mouse still uses two physical buttons for the primary left-and-right click functions. The Microsoft design also has no support for gesture recognition. The only real similarity between the Arc Touch Mouse and the Magic Mouse is that both have touch-based scrolling, and in that regard we find Microsoft's design innovative and more satisfying to use.
As you might imagine, to scroll you simply drag your finger down the Arc Touch Mouse's metal tab. Like the Magic Mouse, the Arc Touch Mouse supports accelerated scrolling, which means you can flick your finger down the tab to scroll more quickly through long documents. Microsoft's design is unique in that it features vibration feedback that mimics both the feel and the sound of a traditional physical scroll wheel. This feature actually gives you a more precise feel to your scrolling, and also lets you know when your finger has left the touch-sensitive tab. If you prefer a vibration-free scrolling experience, or a different scrolling speed, you can adjust both in the mouse's software.
Though we found the Arc Touch Mouse's scrolling generally effective, it's still easy to lose touch of the tab. We also had two brief instances in which half of the tab stopped responding, although in both cases it woke back up in less than a minute. Neither annoyance is a problem with the actual physical scroll wheel, and thus we still prefer that design--Logitech's especially.
