by Surface, this special edition Arc Touch Mouse is designed for life
on the go. It uses Bluetooth 4.0, so it works from up to 30 feet away,
and the BlueTrack Technology1 lets you use it on rough wood
or carpet surfaces. The touch strip uses haptic feedback to scroll
vertically. And it's easy on the wrists, shaped to match the natural
curve of your hand. When you’re done working, just flatten and slip it
into your pocket or purse.
