Young Kim talks about the design process behind the Arc Touch Mouse.
And, here's a first look video of Arc Touch Mouse. The Touch folds flat, to about the same size as an HTC Touch phone. Where old Arc Mouse fit well in a front pocket, Arc Touch will do well in a back pocket. The folding portion of the mouse has 90 articulated pieces and snaps to a very solid feeling and natural arc. Between the bottons, a touch strip allows you to scroll or flick through your Windows, or touch the top or bottom of the strip to Page Up/Down. This refresh includes haptics, so you can actually feel (and hear) the page scrolling and BlueTrack so the Arc will track on almost any surface. The dongle for Arc Touch is the very slim profile dongle as was used on the Arc Keyboard.
