Designing a notebook computer’s trackpad out of textured glass is a brilliant innovation. Not only is it easier to clean than a traditional trackpad, but it is also more durable with no painted surface to stain or discolor. Multi-touch capabilities are what tightens the functional gap between this trackpad and an external mouse. Use two fingers to scroll, zoom, rotate, or right-click. Swipe with three fingers to flip through photos, or use four fingers to expose your desktop, view all open windows, or switch applications. Without a separate button, your hands have 39 percent more room to move, while the ability to click with your thumb remains the same.
