MS has announced Two new mice – the Sculpt Comfort Mouse and Sculpt Mobile Mouse- both of which are optimized for use with Windows
The Sculpt Comfort Mouse is the first mouse to feature the new Windows touch tab, a touch-sensitive strip for navigating through Windows 8. Tapping the center of the tab will switch users between their current app and the Start screen, while swiping up or down can be used to manage open apps.
Meanwhile, the Sculpt Mobile Mouse features a dedicated Windows button for quick access to the Start screen.
Both mice are available from Microsoft’s online store for $40 and $30 respectively.
