Microsoft Wedge Touch Mouse
The first time we grasped Microsoft’s Wedge Touch Mouse, our fingers overshot its buttons by a good inch and a half. The device has only enough room for your thumb and one finger to grasp either side and for your index finger to rest on top.
Touch capabilities are limited to just four-way scrolling: Slide your finger left or right to scroll horizontally, or stroke toward you or down and away to scroll vertically. There’s no pinch to zoom, browser history, or media-player control features, for example.
