The Microsoft Explorer Touch Mouse mixes features from the company's multi-touch Touch Mouse with more traditional input methods, with mixed results. It's a comfortable, ergonomic mouse, with smooth control, and standard, responsive left and right buttons that take up most of the front of the mouse. What's different is the replacement of the scroll wheel with a flat touch strip down the middle of the mouse. The strip can be used for scrolling, has programmable buttons, and includes haptic feedback (which can be disabled). Overall, the scroller works as advertised, though it still feels less precise and reliable than a traditional scroll weel. It can also become slippery with continued use, making it a little hard to scroll accurately. Nevertheless, it's an interesting attempt to reinvent the mouse without making it completely unfamiliar, and at current prices of about $20, it's worth trying if you find tablet-style touch scrolling more satisfying than using a traditional wheel.
